Product: Debt collection

Good day, I am writing to complain about a bill from XXXX  or XXXX XXXX, for {$100.00} for internet/cable/home phone services from XX/XX/XXXX to XX/XX/XXXX, which they sent to a collections company, Sunrise Credit Services, in XXXX, XXXX. I disputed this bill with XXXX  credit bureau, but XXXX is still insisting I'm owing them that amount. I also insist that I do not owe this amount to XXXX, because I had officially cancelled my services with them in XXXX, XXXX and I paid my last bill to them in same XXXX, XXXX for {$100.00} that ended on the XX/XX/XXXX cycle. 
My brother had transferred his XXXX  account to my home, since he was moving from his apartment, in XXXX, XXXX, and had gone to our local XXXX  office to cancel his account at his former place of residence, and start the new service at my home, since he was moving to my place. We spoke to a XXXX  representative, XXXX with code XXXX, about these changes to make sure we are not being billed twice at the same address, on XX/XX/XXXX, and she said I did not owe anything and they took care of the changes. XXXX  had insisted I needed to cancel my service before my brother could start a new service at my residence, since there will be only one service in the house. However XXXX  did not cancel the two services, ( my own and my brother 's own ) at the time we asked them to cancel them, but instead decided to start me on a new billing cycle and charge me for it, and start my brother 's new service on XX/XX/XXXX at my home address. So tentatively, XXXX  was charging me separately and my brother separately in XXXX, for one service in the same residence. At the time my brother started a new service at my residence, I also asked XXXX  to add the home land line to the service, which mea n't they had to port it from XXXX Phone Co, the original carrier. However, it took XXXX over two months to port the land phone from XXXX, after they ran me around and gave me a temporary number that was attached to the XXXX XXXX line. So basically, it was the XXXX phone number that was still working, and not the XXXX  temporary number, since they had still not being able to port the number from XXXX. XXXX  was only able to port the land phone sometime in XXXX, XXXX and I was still paying XXXX, while XXXX  also wanted me to pay them too, even though they could not port the phone, blaming XXXX for not giving them access. XXXX told me XXXX  never made a request to them to XXXX the land phone, so I was being tossed around between both companies, until I reported the issue to XXXX. XXXX  had also taken my name to a collections company in XXXX, XXXX for the amount I feel they are wrongly charging me for, when my brother is now paying the bill in the house for the internet, cable and phone services in the same month of XXXX, XXXX for which they billed me. XXXX  is trying to take advantage of us, even though they promised us that they took care of everything and that we did not owe them anything, when we contacted them. Instead, they still went behind us and made the changes to benefit them, and not keep their promise to us. So, XXXX  is wrongfully charging for the same services twice in the month of XXXX, XXXX, at one place of residence. My brother already paid for the XXXX, XXXX services. So, today XX/XX/XXXX, my brother and I called XXXX to complain about these charges, and spoke to XXXX, with code # XXXX %, in the billing leadership department and the supervisor XXXX, with Code # XXXX  and they could not help resolve this issue, even after we explained all that I wrote above to both of them They both told us they don't have or keep phone records, even when we told them to check the phone call we had with XXXX on XX/XX/XXXX, to confirm that she had told us everything was taken care of, and we did not owe them anything. All the older XXXX  equipments were also returned before the due dates, but XXXX also tried to lie about that too, saying that the equipments were not returned on time. XXXX  is lying about not keeping phone records, because it says that the discussions one has with them on the phone is being recorded, so I don't know why they lied about that too, if they are not hiding something from us. XXXX  has caused me a lot of inconveniences and money by taking my name to collections for this fraudulent amount they are charging me, that has affected my business and other things I'm trying to get done, and if I knew they were this bad, I would never have had any dealings with them, and I hope not to again, after this is taken care of. No one has ever taken my name to collections before because I try to pay my bills on time or even if late, at least they get paid.
