Called me once at 6 in the morning. I didnt answer, so he called again 20 minutes later, waking me up again. He asked for someone named (Madison, I think).. I told him he had the wrong number. He called 3 MORE times before I blocked his number.

This is legit.  Fairview Hospital, calling to schedule an appointment for a procedure that my primary care doctor (who is also part of the Fairview system) recommended I get during my last checkup.
