Who called from 3170000000

I got this number on my caller ID and yet the number is unavailale and they have no ID ! they said something about an auto group survey!! i told them I can report them and to take me off their calling list!

Have had 3 calls from the 0 number. Nothing there when answered. Hitting ignore button from now on.

Called me at home and my cell phone.  I didn't pick up and they didn't leave a message.  The scary part is that only few people now my cell phone number.
