I have been receiving phone calls from them. they ask for me and then immediately ask me to verify my social and date of birth. They refuse to tell me who they are and when I tell them Im not giving them that information, they say sorry we wont be able to help you then. I have yet to receive any correspondence from them in the mail for whatever it is that they are calling about. I have already contacted the credit bureaus to inform them that there is fraudulent activity from this company. I dont know where to begin to challenge the validation period because they havent sent me any correspondence. Any guidance???????????????
