I cancelled my XXXX XXXX on XX/XX/XXXX, at the time of disconnection they provided me the amount of my outstanding balance, which I paid via credit card over the phone. Today ( XXXX ) I received a collection notice from Credit Protection Association L.P. on behalf of XXXX XXXX. When I called XXXX XXXX they informed me that they made a mistake in the calculation of the final payment due, and adjusted it after I made the final payment. XXXX XXXX NEVER notified me I owed anything else, no mail, no email, no phone call -- they just put me into collections. I made the payment today, I would have made it sooner had I known that I owed them money. Putting me in to collections without ever sending me a bill is unethical, and now I have damage to my credit rating through no fault of my own.
