Who called from 6093736500

People calling from this number have been incessant. They call 5 to 7 times per day and leave no message on our cell phone.
Finally, I called them back and get India dialect people asking questions about people we know in college. I advised them they are telemarketing and they don't care. Looking for a sucker!

These people call me every day incessantly. It's so annoying

This number didn't leave a message, so I'm thinking it was spam.

I received a call from this # . A man asked " how are you today" , I answered, but got disconnected! When I tried to call back, I got a one word automated response - " goodbye"  ! Very strange.

Repeat calls with no voicemail. I've cross referenced this number on the internet and it seems to be spam
