I received a call this evening from this number, "Unknown Name" a recording asked for me by name, didn't identify who was calling and told me to dial in the last 4 numbers of my social security number to verify I am who they asked for while implying someone was waiting for the verification on another line.... sounds like somebody trying to "fool me" and fool a third party by getting me to verify from y own number with a third party infringing on the call for illegitimate purpose. Anyhow, I don't follow the directions of unidentified callers and I keep my persona information confidential . I'm not going to pay for the identity of the caller .
