Optimum headquarters and corporate office in Long Island City New York

Optimum Headquarters and Altice Name Change Note

Optimum’s headquarters are located at 1 Court Square West in Long Island City, New York. Older pages and customer searches may still refer to Altice USA, Altice corporate office, or ATUS, but the company changed its corporate name to Optimum Communications, Inc. and now trades under the ticker symbol OPTU.

For most customer-service issues, customers should start with Optimum’s regional customer support, the Optimum app, online chat, a local Optimum store, or the support route connected to the account. The corporate office phone number is more appropriate for main office, investor, legal, executive, media, employment, business, or higher-level escalation questions after normal customer-service channels have been tried.

How to Escalate a Complaint with Optimum

If you have a complaint about Optimum involving internet service, TV service, mobile service, billing, cancellation, equipment return, outage credits, technician appointments, installation, service quality, account access, modem or router issues, number porting, collections, refunds, or customer-service follow-up, start with the support channel connected to your service area. Keep your account number, service address, billing statement, order number, cancellation confirmation, equipment return receipt, chat transcript, technician appointment details, and any case numbers.

  1. Start with regional support: Call the customer-support number for your service area or use Optimum chat through the official website or app.
  2. Use the Optimum app or account portal: For billing, payments, service status, WiFi management, and equipment details, use your online account when possible.
  3. For outages: Check the Optimum outage map and document the date, time, service address, and outage impact before requesting credits or follow-up.
  4. For cancellation or equipment returns: Keep confirmation numbers, return receipts, tracking numbers, store receipts, and photos of returned equipment labels.
  5. Ask for escalation: If the first contact does not resolve the issue, request a supervisor, case number, retention/cancellation confirmation, or written follow-up.
  6. Use corporate office channels when appropriate: Written corporate correspondence may be directed to Optimum Communications, Inc., 1 Court Square West, Long Island City, NY 11101.
  7. Escalate externally if needed: If a communications-service complaint remains unresolved, consider filing an informal complaint with the FCC or contacting the applicable state consumer-protection or public utility office.

Optimum Complaint Themes from Reader Reviews

Recent reader comments on this page are mainly complaint-focused. Common themes include billing disputes, continued charges after cancellation, difficulty getting supervisor help, problems with vacation-mode or reduced-service billing, charges after equipment returns, account corrections after a family member’s death, and frustration with customer-service follow-up.

Because many Optimum complaints are account-specific, readers should keep written proof such as billing statements, cancellation confirmations, return receipts, chat transcripts, payment confirmations, and case numbers. Do not post account numbers, service addresses, phone numbers, full bills, or payment details in a public review.

Optimum Billing, Cancellation, and Equipment Return Issues

Billing, cancellation, and equipment-return complaints are common for cable, internet, and mobile providers. If you cancel Optimum service, ask for a cancellation confirmation, final bill estimate, equipment return instructions, and confirmation that autopay or recurring billing has been stopped if applicable.

If you return a modem, router, cable box, remote, or other equipment, keep the store receipt or shipping receipt. If the account is later charged for unreturned equipment, provide the return date, tracking number, serial number if available, and proof of return through official Optimum support channels.

Optimum Outages, Service Quality, and Technician Complaints

For outages, slow internet, intermittent service, TV problems, phone issues, installation delays, missed appointments, or technician complaints, document the dates, times, service address, equipment used, outage map status, technician appointment window, and troubleshooting steps already completed.

If service problems continue, ask Optimum for a case number and written explanation of the next step. If the problem involves repeated outages or chronic service failures, keep a log of service interruptions and any credits or repair appointments promised.

Optimum External Complaint and Regulator Options

Optimum provides internet, TV, mobile, and phone services, so external complaint routes can vary by issue and state. The FCC accepts consumer complaints involving internet, TV, phone, accessibility, billing, equipment, number porting, and related communications-service concerns. State attorneys general, state consumer-protection offices, and local franchising authorities may also handle certain cable, billing, service, or deceptive-practice complaints.

Optimum Fraud, Scam, and Account Safety Tips

Be cautious of fake Optimum support numbers, spoofed calls, fake outage-credit texts, phishing emails, fake bill-payment links, fake technician messages, and websites pretending to be Optimum. Scammers may try to collect payment card numbers, account passwords, Social Security numbers, or one-time passcodes by claiming your service will be disconnected.

  • Use Optimum.com, Optimum.net, the Optimum app, or a verified Optimum store for account help.
  • Do not provide passwords, one-time codes, full card numbers, or Social Security numbers to unsolicited callers.
  • Verify any shutoff, payment, refund, or outage-credit message by logging in through the official Optimum website or app.
  • Be careful with search ads or phone numbers that claim to be the Optimum complaint department but are not listed by Optimum.
  • If you see an unfamiliar Optimum charge, compare it with your bill, service agreement, mobile account, equipment return records, and card statement before disputing it.
  • Report suspected internet fraud to the FTC or the FBI Internet Crime Complaint Center when appropriate.

Optimum Disappointing Return Issues

May 1, 2025

Optimum, Billing my dead mother for TV Service for several months now, however I’m not sure how such service can be provided since you already received the boxes back months ago. I have sent the Death Certificate as requested. This has cause me excess stress, anxiety and mental anguish on top of the grief of losing my mother. I have done everything requested of me and you still you can seem to get her account correct. FYI – Optimum also owes her because you were billing her for 4 boxes and she only had 2. This has been going on for almost a year and I have wasted a ridiculous amount of time on the phone with your staff who said she would be credited and has not. We have been customers since the start of cablevision and even a Director for New12CT at one point. So you will be losing a whole family of loyal customers. Sad what has become of this company.
