Rue 21 Corporate Office Headquarters

I recently received a call from your maintenance company,1stop facility maintenance, about repairing a drawer facing your Lagrange ga store. I jumped through all the hoops, submitted huge amounts of documentation that were required by them, and went and did the repair in a timely and professional manner. I was told they are a net45 company so I waited well over 45 days after I invoiced them and I have not been paid. they no longer reply to any correspondence and I'm left with no other option but to start procedures to place a lien on the property. I really don't want to do that if someone could speak with them and get this handled it would save us all a ton of misery thanks
