Received a debt notice XXXX/XXXX/15 for a medical service rendered over 5 years ago. This is the XXXX notice of any debt related to unpaid claims. Deadline of XXXX/XXXX/15 to pay or be reported to credit bureau. Requested proof of the debt. They said they will mail it to me but I wo n't receive it by their deadline. This situation seems like a scam. I called XXXX and was treated rudely each time.
