Back in XX/XX/XXXX 2015 I XXXX and due to being on a collection XXXX ended up going to XXXX. There I did give my information ( medicare ) and I got my XXXX XXXX XXXX XXXX. The morning after the XXXX had already come off ( shoddy work ) and after a days work I only had XXXX left ( I ended up having to XXXX myself ). Month or two later I get a bill XXXX where they want {$340.00} from me. I promptly respond to the bill asking them to explain. What I got from them was what I am including as an attachment ... .i.e. a very cryptic itemized invoice that explains nothing. It does show the XXXX ripping off medicare for XXXX and me for the rest! I wrote them back telling them thats not going to work. That was the last I heard from XXXX. 
Later I get a letter from RCMC ( collector ) asking for the money. I go through the same process of writing to them and last week I get notified they have added this to my XXXX credit file.
