Who called from 5712295673

They called me and said they were from the yellow pages and they asked me if I am josef federsel I said yes and they hung up.

DON'T CALL HERE ANY MORE

Repeated calls no one there,  I tried to call them back it says "this is not a working number ".

I did answer the phone as a business and they still hung up!

These people call atleast 3 times a day and leave no message and if I do answer they hang up. Its been going on about 6 months now and I would like them to STOP!! It is so frustrating and uncalled for! They don't say who they are or even acknowledge you when you answer, I just want to report them and have it end! I am on the DO NOT CALL LIST, yet they keep calling...
