Who called from 8475488352

This number has called me 5 or 6 different times of the day. Sometimes late at night and other times during the day. I answer the call and it's silent on other end. Every single time.....

answered call from this number and they hung up.

Ditto here, I receive calls from this number regularly (about once a week for a few months now). Tried answering once, no reply.
