credit acceptance rip off suitland Nationwide

I thought this company was ok. This was my first time and last time i will ever deal with this finance company. I asked them for an pay off amount and then i paid the amount in full before the pay off date (CONFIRMED WITH THE COMPANY) and i thought everything was ok intell i recieved a call a month later talking about i owe them 2500. I told them the details and they said they would check into it for me. long story short i called them every 3-5 day for 1 and 1/2 month and it was never resolved. then this last call they told me that i did not pay in full. i explained everything and they said the first payment was before the pay off amount but i asked for a pay off before i made the first payment and it was western union. i really dont get this company trying to mess people over like this. i told him ok if i pay how much is it "2500 he said" cause western union only allow 2500 at the most. he said "you can make that in one payment" i said i need it in writing before i make that last payment and he said ok let me check and he came back and said ok your total is 2503.77 if paid today. I told him this is the kind of trick i told him i didnt want when i firsted talked to him.this company is all a bunch of tricksters. DO NOT USE THIS COMPANY UNLESS YOU DONT LIKE YOUR MONEY.
