Product: Debt collection

On XX/XX/XXXX I opened* an account with XXXX XXXX in an attempt to switch cellular providers. After receiving the first billing overview, and per the Device Payment Agreement Terms, it is the borrowers right to cancel within fourteen ( 14 ) days. In exercise of this right I decided to cancel* the XXXX XXXX XXXX on XX/XX/XXXX because the billing charges did not match the information advertised military rates when I signed up. I placed a call to XXXX ( XXXX ) to confirm if the charges were accurate ; spending twenty-five minutes on the line ( attachment D ). I  returned the three devices, and was refunded the {$800.00} that I paid towards the devices. The {$800.00} refund* posted my credit card on XX/XX/XXXX. 
I received a phone call* from a XXXX XXXX ( XXXX ) representative questioning why I have not used the phone lines that I established ; he was advised that the lines were cancelled. In a letter dated XX/XX/XXXX from XXXX XXXX states, Our records show you have not used the line/s you recently activated*. I then received another bill* from XXXX identifying each phone number as being cancelled, yet they were still charging me unused service which I cancelled on XX/XX/XXXX, in the amount of {$420.00}, and an additional {$1000.00} for devices that I returned on XX/XX/XXXX. 
In response to a letter* dated XX/XX/XXXX I called XXXX XXXX XXXX XX/XX/XXXX at XXXX ( 22min ) ; XXXX at XXXX, XXXX, XXXX, XXXX, XXXX ; XXXX at XXXX. This letter threatened to send my supposedly closed account to collections. I spoke with several people XXXX ( XXXX ), XXXX, XXXX and others to resolve this error because the account was closed on XX/XX/XXXX.
