Quest HQ - Issues With Payment Plan

December 13, 2022

I set up a payment plan with Quest on Friday 10/21/22 with my debit card. When I checked my bank statement I found that Quest took the entire amount from the statement and not the agreed amount on the plan. It is now Wednesday 10/26/22 without a resolution. I have called numerous different numbers and left numerous messages without a return call.
