EX refused to investigate a dispute. They said it has been previously investigated and was verified by the creditor. I sent the CA a letter requesting validation of the debt. Letter was received and accepted in their offices. No response in over a month. I sent copies of the letter, copies of the CMRRR and green card. I called today and they said that they need something from the CA about the account. I tried to explain that the CA has not responded and there is nothing that the CA can send about the account. How can I get these items removed? Do I need to send an ITS? Please help!!!!!
