I had an issue with an account that I had with a gym membership. My account was transferred over to First Credit Services and they tried charging me for the full length of the contract, even though there were still 30 months left on it. I asked Vinay (the reps name) "how can I pay for services that aren't even rendered yet? There's obviously a mistake that needs to be corrected" His response was in a tone that was rude, snub, and demeaning. He asked me "How can a company can only submit the full amount of the money owed and not partial (which I can see possible)" He also told me not to contact the company that submitted the report. I asked why and he said because they can't do anything about it and I need to pay the $1,000 to First Credit Services. I contacted the gym and was able to rectify the mistake, that Vinay from First Credit Services falsely stated I couldn't.
