This number just called. Caller id said SSI. I did some checking and they are Survey Sampling Research Group. They call from multiple telephone numbers. There are two things, though. I heard from one of my friend's relatives that if you answer the phone, it'll cost you money. Also, if you do answer, it's always a dead line. Just a heads up.
Caller sounded very unprofessional, but asked for me by (first) name. She claimed to be representing Blue Cross - Blue Shield of Louisiana, and wanted to ask me a few questions.
When I said I did not feel like answering questions, she was polite and agreed to end the call.
