XX/XX/XXXX I signed up for XXXX DSL Internet service. I choose to pay for my equipment XXXX the XXXX router ) at the beginning of my service. When self installing the service, I discovered that the DSL service did not properly work and called XXXX to which they decided to dispatch a technician. An XXXX technician, named XXXX, came to my house and acted in a very professional manner to resolve the issue. He ran a line up the side of my house because he said the earlier connections were not properly installed. My service worked and I continued until XX/XX/XXXX, paying all bills on my personal XXXX card. XX/XX/XXXX I decided to cancel my service for a competitor 's better connection speed. I called XXXX customer service around XX/XX/XXXX to cancel to which I was told " please keep your XXXX router if you ever decide to come back ''. This was my understanding, as earlier stated, because I had paid for the equipment at the beginning of the service. XX/XX/XXXX my XXXX card was charged for {$160.00}. Upon inquiry XXXX, I was made aware that the charge was for unreturned equipment XXXX. I disputed this charge XXXX and was instructed, XXXX to call XXXX. I spoke with a customer service representative XXXX who told me that " multiple emails had been sent '' ( these emails were sent to my XXXX email address that I no longer used because I no longer had the service ) about me owing. I asked this rep to check my bills to confirm that I had paid for the equipment at the beginning of my service. He did confirm that I had paid at the beginning and that they could refund me one of two ways, either by credit to my XXXX card or via paper check. I choose to have a credit to my XXXX card which I was told would take up to two weeks. After two weeks upon non-receipt of the refund, I disputed the charge XXXX and explained to them the process I had been through with regards to dealing with XXXX customer service. XXXX let me know, via XXXX mail about 2 weeks later, that they had found in my favor as the merchant XXXX had not responded to my dispute. On the XX/XX/XXXX I received a letter XXXX about the {$160.00} dollar debt still being owed. I reached out to XXXX customer service to explain the situation. Again I was told that I owed the money until the rep reviewed the notes and account to find that I had been mistakenly billed. She let me know that her manager would reach out to me within 1-2 business days. As it stands, XX/XX/XXXX, I still have not been contacted XXXX. I have since been contacted by a Credence Resource Management about the collection of a debt owed XXXX. I have been called XXXX every day for the last 5 days. The gentleman I spoke to from the company took an unprofessional tone with me and let me know to file a written complaint to resolve the issue. I took issue with his tone of voice and aggressive tactics. I have chosen to ignore the phone calls I am continuing to received from Credence Resource Management.
