Resurgent Capital Services L.P. Debt Collection Complaint

Resurgent Capital Services L.P. Debt collection department,

Credit card Disclosure verification of debt Not given enough info to verify debt Florida

I had an old dept. and a collection company bought the dept., I challenged them with a letter in accordance to fair credit Act which they had 30 days to respond under federal law and they had to remove it from my credit reports. They have not removed it and they have not responded. I tried contacting them but they are very rude and no resolve.
