My question involves collection proceedings in the State of: Oklahoma and Georgia.

In 2003 I was living in Oklahoma and became unemployed and couldn't make payments on a credit card. In 2008 I got a letter from a Law firm in Atlanta,Ga(I live in GA at this time). It states to show up in court or sign this paper and start making payments. I agreed to make a monthly payment of $250.00. The original debt was $4,900. Now I must ay this law firm $15,700. I have been making payments for 13 months now and the debt disapperaed off my credit report. I want to know can I take them to court and get the amount reduced. I am paying back TRIPLE the original debt???
