Receivables Performance Management LLC Debt collection department,

Credit card Cont'd attempts collect debt not owed Debt was paid Kentucky

I settled an old credit card account. We agreed on a payoff amount on certain date. I have the letter stating the agreement. The amount was paid, taken from my checking account on the date agreed upon. 3 months later I am getting calls from other collection agencies trying to get the balance of this same account. I have called the collection agency that I worked with initially and they were supposed to send me letter stating this was paid in settlement agreement. They will not send the document and it is still showing on my credit report as balance owed
