Signed up for XXXX XXXX XXXX service on XXXX/XXXX/15, activated account on XXXX/XXXX/15. Cancelled my service on XXXX/XXXX/15 after receiving XXXX bill with a service I did not agree to. Cancellation was approved by their retention center ( after buyers remorse period ) due to the misrepresentation of the service agreement and assured me no balance will be owed once the device was received by their warehouse. I returned the device on XXXX/XXXX/15 using their provided return label by a third party shipping service Newgisitics via XXXX. I called back to check on the status of the return of the device more then XXXX different times, XXXX XXXX XXXX reps responded that the tracking could not be located to " call back ''. Finally on my XXXX attempt on XXXX/XXXX/15, over a little 30 days from the cancellation date of XXXX/XXXX/15 I was recommended to open a " case ticket '' to track and locate the device. I was assured by the rep at this time, that the account would be suppressed due to this issue and that no collections would be attempted. On XXXX/XXXX/15 I began to receive daily calls by a XXXX number with no message left, I finally decided to call back on XXXX/XXXX/15 and it was GateStone, a third party collection agency hired by XXXX XXXX XXXX XXXX collect a debt. I notified them about the " case '' of the missing device and the Gate stone rep was kind enough to suppress the account till XXXX XXXX XXXX recalls the debt from them which I was told could be done immediately. I then called back XXXX XXXX XXXX on XXXX/XXXX/15 livid at the situation as they assured my account is suppressed till case had been cleared. I was told I would get a call back about the situation. After a few days and no call, I called XXXX XXXX XXXX back on XXXX/XXXX/15. The XXXX XXXX XXXX rep reviewed notes and stated the " case by investigation team '' noted the account on XXXX/XXXX/15 that the phone was located in their warehouse on XXXX/XXXX/15 and that a full credit and refund would be administered in XXXX billing cycles. Yet, they could not recall my account from a third party due to closing and paying out my account to the third party collection agency and now the debt is owed to Gatestone. I conferenced Gatestone and the At XXXX XXXX rep to relay the status on the account that a refund will be placed, account is now at zero but the payment must still be made to them direct from me. YET, after having reported the device was received and in good working condition, they still sent my account to a third party collection agency. I do n't understand why XXXX XXXX XXXX refuses to recall the account from the collection agency rather have me pay them direct for a debt I I never owed!
