Received credit report and noticed that an account was turned over to collections. I was shocked and appalled. Do not recognize this account. However I do recognized XXXX XXXX XXXX XXXX of XXXX. Services were provided in 2013. I never received any notices that bill was past due. I also felt that XXXX XXXX XXXX XXXX XXXX XXXX was to have filed a claim on my behalf in accordance with MEDICARE procedures. I checked with MEDICARE and was informed that they show no records of any claims in the amount of {$850.00}. XXXX stated that in order to process bill, I must completed the XXXX form and return along with the bill. No correspondence ever received stating that claim had been denied. Lead to believe that bill had been processed. Feels like I am getting the run around and am being penalized for the non-actions of others.
