EOS CCA asked for verification of my address and last XXXX of social. They said they take care of private personal matters but never disclosed this was to collect a debt. In addition when asked repeatedly what company they were calling on behalf of, they said they could not reveal that information. I said that is the law but they still refused to give the information. I said I would not be verifying anything until they mentioned the client they were calling on behalf of since I do n't know what EOS CCA is.
