Product: Debt collection

In XXXX of XXXX we switched our wireless provider from XXXX to XXXX XXXX XXXX. In doing so we then returned the 3 devices and an ipad back to XXXX using their mailing coupons that they provided, and later came back and stated that we did not return them, and I needed to provide them with the tracking number. I stated to them that they are the ones that provided the mailing labels. A few months went by and since I and XXXX could not come to a reasonable final billing they turned my account over to a collection agency. I was contacted in XXXX regarding this debt at which time I stated that I did not owe for the phones and was NOT paying that amount but would make good on the final bill. Thus said, XXXX, XXXX XXXXt XXXX agreed to a settlement of {$1500.00}. Allowing me to make 4 payments of {$370.00}. My first payment was made on XX/XX/XXXX, 2nd payment was made on XX/XX/XXXX and XXXX payment was made on XX/XX/XXXX, However, my 4th and final payment was not processed by XXXX due to XXXX recalled the debt, to which I did not find out until XXXX of XXXX. I called XXXX to inquire about this and they kept saying I had a final billing of {$1800.00}. I explained that I had made my payments as promised to the collection agency in which XXXX says, they no longer have the debt. I hung up disgusted as after many, probably 25 plus phone calls to XXXX to try and settle this matter, which were all ditched efforts, I gave up. I was contacted 2 weeks ago from a new Collection agency that XXXX has hired Source Management, to which they are now claiming that I owe XXXX {$1000.00}. I stated, " I do not owe that amount I have already tried to rectify this with XXXX and that obviously XXXX has not given them the correct records, and tthhat I would contact XXXX. I was called again today by Source after me trying for the last week to speak to someone at XXXX that speaks in English or at least someone I could understand and GOT NO WHERE ... .I explained or tried to explain to Source Management that I do not owe that much and I had a settlement with a previous collection agency and XXXX recalled the debt before the last payment was processed. The representative from the collection agency XXXX was extremely rude and did NOT have her facts together at all. I then demanded to speak to a manager. Once I spoke to the manager, still not getting anywhere I disconnected the phone, called XXXX   again, and stated my whole case again, for some strange reason I was disconnected and then attempted to call back 4 different times and put on long holds only to be told I had to call this new collection agency to settle the {$1000.00}. If anything at all I only owe the last payment of {$370.00} that was never processed by XXXX prior to XXXX recalling the collection attempts in order to try and resell the debt to collect more money. this matter has already been turned over to CFPB when XXXX had it due to XXXX would not remover the remark. At that point when CFPB contacted XXXX and the remark was removed from my credit report along with a letter from XXXX that the account had been settled in full. I tried to explain this to Source, but to no avail, uneducated employees that do nothing but call people and speak to them using scare tactics and deceptive debt practices to which is against the law is all you get from these folks. The debt was cleared by XXXX.
