I was involved in a small fender bender while driving a rented car from enterprise leasing while I was back in between XXXX in XXXX. It was just a small fender bender and no one was hurt and only small scratches to the bumper as confirmed by the police report. I had purchased the rental insurance at the time of renting the auto and I had my own personal insurance through XXXX as well. The accident happened XX/XX/XXXX. I went back oversees on tour and while away I was sent a collection letter from a company named XXXX claiming I owed {$28000.00} dated XX/XX/XXXX. I did not see the letter till I returned and was shocked. I called and explained that I didnt owe them anything I had insurance and they didnt care. I called XXXX and they said they couldnt find any record of anything and then I contacted XXXX. XXXX looked into it and they were sent the claim. They refused to pay the claim becasue they said it was too high and frivolous. They claimed that if I was served or sued they would pay the claim but thats it. I consulted an attorney and they were unable to do anything. I went back for another tour and just figured I would have to wait and see if they served me. When I got back nothing had happened. So I went to get approved to buy a home and when they pulled my credit I was shocked to find that the collection was showing from XXXX on my transunion credit report. It wasnt on any of the others but none the less it was keeping me from getting a mortgage and buying a home. I disputed the account through transunion twice sending the proof that I didnt owe anyone because I had insurance. They just verified the information both times and I still cant get approved on the mortgage. I had to end up renting again and paying more than I was going to pay for buying a home. Please help me get this off my credit report it is not fair and shouldnt be on there. It has nothing to do with me not paying a loan and its clear that I dont owe it because insurance should have already paid it. Lastly they did all of this to me while I was XXXX. Please help.
