They call from this number-(111) 111-1111 several times a day. When you answer, no one will say anything, but they will call back in a few minutes.
They called me 2 days in a row. On the 3rd day they asked me to call back if I had any questions so since I didn't have any, I didn't call back. Now on the 5th day in a row they are calling again. I already submitted a request to delete my number.
