Numerous calls over many months, no message left on answering machine

i hear background sounds maybe recorded don't say anything just phones repeatedly.

Received a call from Steven with an East Indian accent today who asked if this was my phone #.  I asked him who was calling & then he said he was from Xcompany but I can't remember the name of company he said.  The he asked was this Mrs _________ .  When I said yes he proceeded to say again it was Steven from X company & there was a problem with my computer.  We had just read in the newspaper this weekend about some scam saying there is a virus on your computer & they try & get you to download something and then get complete access to your computer. I said there was nothing  wrong with my computer and hung up, he immediately phoned back but I just hit the talk button & then the end button.

keeps calling my house line and my cell..... never leaves a msg. when i call the number back it has a recording saying the number is not in service.

Called and asked if I had a Microsoft computer. I told them I don't own a computer, they hung up.
