Who called from 7653744112

Received call and they hung up. Called back and they hung up again.

The number is Riverview Medical Group looking for a payment on an outstanding bill.

This is the bill collectors for Riverview Medical Group.  They mailed me a bill for a relative (to my address).  Then they called me to try and collect.  They asked for the relative and I tried to help get the bill paid.  They hung up on me.  Very rude and unprofessional.
