I discontinued my telephone and internet service with XXXX XXXX in XXXX of XXXX. I paid the XXXX bill of XXXX on XXXX/XXXX/XXXX. XXXX XXXX TV was bundled with XXXX XXXX phone and internet service and it took 2 months for them to stop billing me for XXXX and release me to pay them directly rather than through XXXX and they would not release me until I had a final bill from XXXX XXXX and had paid it. I paid XXXX XXXX XXXX on XXXX/XXXX/XXXX and XXXX on XXXX/XXXX/XXXX. I was told at that time that I had paid all I owed. I paid my XXXX bill for XXXX to XXXX on XXXX/XXXX/XXXX and continued to pay them from that point forward. In XXXX of XXXX I received a notice from a collection agency demanding payment of {$51.00} due to a balance due on my account with XXXX XXXX. This was 9 months after I had discontinued my service with XXXX XXXX and 7 months after I had been told by XXXX that I had paid the final bill with them. Rather than contact or bill me directly, they turned what they claimed I owed them over to a collection agency. I spent over an hour on the phone with several different people at XXXX XXXX trying to get an explanation for the charge. I was finally told that the amount came from money they paid to XXXX on my behalf. The problem is that I never missed a payment to XXXX. I had paid XXXX for XXXX and XXXX and then I paid XXXX directly starting in XXXX of XXXX. If XXXX XXXX paid money to XXXX after XXXX then they paid money that was n't owed and they need to talk to XXXX about refunding it. XXXX XXXX reported me to the credit reporting companies and my credit rating took a big drop from almost XXXX to under XXXX. I contacted the agencies and disputed the debt. They researched it and deleted it. My credit rating went back up to over XXXX. Then XXXX XXXX turned my account over to another debt collector and I got another demand for payment dated XXXX/XXXX/XXXX from the new agency. I assume they will report me to the credit agencies again and I will have to go through the whole process again. I do n't owe them any money and it is nothing short of harassment for them to be demanding payment from me. The debt they claim I owe is the result of their inability to manage their own account records.
