Get a call everyday, but no response or message.

called asking for personal information.  when I asked about what the call was regarding , the lady said that she couldn't give out information over the phone untill getting my address & last four digits of my social. so I told her the same..

I keep getting calls from this numbers, let it go straight to voicemail and nothing. Refuse to pick up.

Calls everyday but leaves no message.  Extremely annoying.

Received a call just now and i had it blocked for some time. I called back and ask what company this is and she says GMC. Then rudely says who is this.... Hung up on her..
