<prompt> Human: So an odd collection agency showed up on my credit report.I made a few calls and found out I have an open account with a hospital but for a different amount. Hospital tells me 600 the collection agency states 1000. The hospital also tells me they dont use that collection agency and that my account isnt not even with a collection agency, that it is being handled within the hospital.I called the collection agency and asked where they got my account from and they told me they got it from a debt buying company. I asked them to verify the debt and they just sent me a piece of paper with my account number and the amount I owe them. How should I further dispute this?1. Should I continue disputing this directly with this mysterious collection agency?or 2. Dispute directly with the three credit bureaus?  <response>: This smells like a fish called fraud. The hospital claims the debt and will work directly with you. nuff said. Tell the other guy to go away. If he doesnt, you then go apply for a card and get dinged because of your bad credit. Then you have a leg to sue the fraud company.
