I called Cox in June regarding account number 750512-08, canceling my Niceville, FL, service as I was moving to Pennsylvania. I was told I did not have to return the modem, as it was mine. I paid my last bill of $38.98 on July 20, 2015. Since then, I have received several bills. I called Cox and was told the modem must be returned and that it did not belong to me. I informed Cox about the incorrect information I received and was told they could do nothing about it. I then received a bill for $145.13 from Credit Control Corporation of Newport News, VA. When I called again, I was informed by the customer service person that I owed the money. I asked to speak to a supervisor and got Adrian, who would not provide his last name, and was given the same information. I asked to speak to his supervisor and was transferred to Carol, whose ID number was 35714 and who also refused to provide satisfaction. She said she would send me a box to return the modem I had been told I did not have to return, but would not guarantee that all charges would be removed. I want the fees removed and any fees charged by the credit company to be borne by Cox. I will return the modem when I empty my storage unit Sept. 21.
