I am now dealing with a 4th collection agency for a debt that I do not owe. I had sent a validation letter to the last agency, to which I had heard no response from. Then I receive a letter from another company - First Performance Recovery - about the same issue (to which I sent another validation letter). The 1st three agencies could not validate the debt; how long am I going to have to deal with these agencies? I have tried contacting the original lender (Sears), who sold it to another company. They will not speak with me, and refer me to the CA they are dealing with.
