unknown caller from San Antonio, TX left no message -- now blocked!

Missed the call 2 days in a row. 3rd day....India accent.. "I am from Microsoft Services. Are you now in front of your computer in this moment?" I answer, "No, you woke me up." Voice says, "Please, speak you more clear, I understand not what you are saying." I state. "I am not in front of my computer because I was sleeping.", Click...He hung up on me. Later same day, "I am from Microsoft Services. Are now you in front of your computer in this moment?". No, I am driving. Voice, "We will call you at a time that is more convenient. Voice hangs up. 2 days later. I miss another call.

How do you block these calls on a land-line?  Get far too many. Make me get up and answer.

Do talk to any one from this number, they will try and get money from you for fixing errors on your PC but will lock up all of your files and you will have to pay them to get then back,  they have nothing to do with Microsoft.
