Who called from 5152934737

Received a call from this number, did not answer, no message

Received another mysterious call.  I get an inordinate amount of 515-xxx-xxxx calls.  Didn't answer this one.  Last nights claimed to be a Clinic that doesn't exist.  Called number right after call.  Number gave me their office hours??

They called me and didn't speak when I picked up and they hung up so I called back and it said I couldn't call that line from my phone

Same here buddy, they just hung up on me when i said they called and i said to stop calling
