Who called from 2108074122

I have no idea who this caller is, but after the 10th call this morning, I blocked them.

Same here, these people should be jailed for disturbing the peace.  Blocked!

This number called my house, claiming to be from Microsoft tech support, sounded like he was from India..  I said I dont need Tech Support, do not call me again.  hung up.  Immediately called me back.. three times.  He told me that he would keep calling until I gave him the information he wanted on my computer in my home because I was having a "tech Problem".

If they claim your system is causing problems, just ask them what your IP address is.  They'll  usually hang up.
Failing that, ask for an 800 number to return the call, as you're busy right now.  They'll hang up--but be prepared for some foul language.

Received 10 plus calls from this number. Screened on answer machine, never left message. Blocked now. Surely this is a scam.
