Who called from 7206055866

Picked up the call because I was expecting a call from a doctor's office. They hung up as soon as I said hello.

Calls, but won't leave a message.
BLOCKED.

Called, no message.  Shows "med clinic" on caller ID.  Yeah, right.

called...id just said denver co...no message

Got a call from this number today (6/9/2017) at around Noon.  Caller ID showed up as "MED CLINIC 1-720-605-5866".  I don't answer calls from any number I don't recognize or that isn't in my phone's address book; so I let it roll thru to voice mail.  Whoever it was didn't leave any message.  Added this number to my phone's Call Block List to stop any future calls from this number.
