We took our XXXX for an emergency but we had to transfer it an emergency hospital and paid the clinic in full. We learned at the hospital that they had lost the blood tests and mishandled the case and told the clinic we did not feel we should be charged. When we got the credit card bill we disputed it and received notification it was resolved in our favor ( see attached document for further details ). We heard nothing until months later we got a letter from a debt collector ( we have filed a claim with you against them already Case number : XXXX ). We called them explained the situation and sent them all the information with a request that they contact us if they needed any further information. Again we heard nothing until months later Identified us about an inquiry which turned out to be a negative report from the debt collector. We contacted Experian and disputed the report. We sent them a complete package of all of the documentation including the paid bill and credit card resolution. They simply sent an inquiry to the debt collector who said the account was valid and had not been paid without reviewing the documentation which showed the debt should never have been sent to the debt collector as the merchant did not respond to the credit card company 's inquiry about our dispute or send us anything once the case was resolved, and the debt collector did not do due diligence when the information was provided to them. We disputed their first finding and they simply repeated the same inquiry which we have now disputed again showing them a perfect credit history except for this XXXX " incident ''. We did the same process with the other XXXX credit reporting services XXXX of which deleted the report after finally reviewing the material. The attached documents have the original payment, the credit card company resolution information and a much more detailed explanation of everything which has transpired. We would appreciate your assistance in getting this negative report removed from our credit record.
