<prompt> Human: I had to go to the hospital and my bill came out to 2000. When I received the bill, I noticed that my insurance wasnt applied even though I provided the hospital with my insurance info at the time. The bill went into collections and of course tanked my credit score. Recently, I received the updated bill from the hospital showing that my insurance kicked in for that bill and now my patient responsibility is 0. The collections company they sent me to though, is Transworld Systems Inc. Ive disputed this with all three credit bureaus and I keep getting letters saying that theyve verified that the debt is mine. Im not trying to dispute the debt was mine, Im trying to dispute that I owe them anything. How do I go about getting this collection removed from my report?  <response>: Did you send them the receipt? Maybe call them in person or send a letter explaining.
