Caller claims that they are doing a market study, but also tries selling you consumer credit services. Told them to remove my name/number from calling list but they won't. Blocked.

Called today. Did not answer and they did not leave a message. Blocked caller.

Called and left no message. I didn't recorgnize the number so I texted to it to call me back. Received no call back.

I have blocked SSI 8 times in the last two months. They call  back with the same caller ID, just a different phone number.

Start blocking area codes.
