Who called from 8642077960

Just got a call from this # not the first one.  No message left  864 is a SC zip code

Called again, left no msg - area code 864 (upstate SC)

this number just rang my phone.  I didn't answer it.  Seems like the caller ID "Med Clinic" may called me on 1 or 2 other occasions and left no message.  Not sure if It was the same phone number.
