I keep getting the same calls saying I owe XXXX different debt, when I ask for information on them they wo n't give me any infor unless I give verify my social security number. I tell them I wo n't but just give me the name of the debt I owe & they say unless I give them my SS # they ca n't release that information. I then asked for the name, address & Company info & they refused to give it to me. The company name that comes up is Concord Resolutions. They tried this a while back but I told them I was going to report them & they quit now here they go again.
