Who called from 2036266549

They called, and when we answered the line was just the dial tone.

caller id says internal medicine.  when i ansered the call,  saying hello , three times, louder every time.  i got a Goodbye

Caller ID said "Internal Medicine" - caller identified himself from MIcrosoft and said that my computer was sending out bad signals.  Would not give me a callback number to verify.  Wanted me to make changes to my computer which I refused.  Likely a spoofed scam call.

scammer, all of today's calls are microsoft scams

It was a missed call and they didn't leave a voice mail.
