I am in the middle of a refi and there is a collection on my credit that is not mine. XXXX is the original creditor and they have given me a letter confirming this is not my debt ( I am actually a current customer of XXXX in good standing ) I contacted the collection company ERC and they refuse to give me anything in writing confirming that they will remove the negative reporting. I need a letter from them so that I can continue the refinance of my home loan as this is affecting the rate I can qualify for.
