This number has been calling me about quite few times and I answered it but I kept getting voice mail or whatever. What's going on and I hope it is not prank calls

I got a call from this number, the person did not identify himself, or where  he was calling from until I pushed him.  Said his name was "David Smith"; with an "asian" accent which sounded a bit sketchy. He did not identify what company he was calling for; he was pushy about me getting to my computer to do something. He would not tell me what was wrong but wanted to know if I was having any problems and how old is my computer...I proceeded to tell him I did not trust him and hung up.  He then called back at least 3 more times; did not leave a message.  I feel this was a prank call...

WE ARE GOING TO REPORT FBI, SOME DAYS WE RECEIVED ABOUT 10 TIMES.

I just had a telephone call from someone representing themselves as from AOL wanting to update my security software. The phone ID was  Gogliettino Joh 203-415-0438, and an Asian woman tried to persuade me to let her have access to one of my computers.

A woman by the name of Linda Grey called stating she was from technical support. I told I did not need her help and hung up. I have been warned about anyone calling to fix my computer. They just want to get in there
