15 months ago I had an accident. The local hospital kept me there for 2 weeks. Every few days they would send me home and I would be back within 12 hours because of the serious infections. Finally I went to Vanderbilt in Nashville and they were shocked by my condition. I spent 3 weeks there trying to recover from what the local hospital did. Last month I had another surgery because I have still not recovered. A debt collector is now calling me and treating me bad and trying to get me to pay more money to the hospital that made me worse. I do not want to pay them another penny for that horrible care. I have problems that will be life long now because of them. What can I do to stop the bills and the calls?
