The caller frightened my elderly mother-in-law, telling her she had a problem with her computer. She informed him she doesn't have a computer. He kept talking and got abusive with her and she hung up.

My national spam-blocker disconnected this call after one ring!

I've played along with them twice now. I pretend to press the keys they ask me to, and when I'm supposed to tell them what message popped up, I've said "oh no, it's a message warning me not to listen to the BS from scammers calling from "Microsft" to help with my computer". Today's response was "OK, goodbye", but when he didn't hang up I asked him if people were actually falling for his BS, he kind of laughed and then hung up. The last time I played along, the response was a bit harsher, the caller actually said "F you and F your mother, you F-er". Part of me was mad at that, but I got a little satisfaction knowing I got to him, even if just a little bit.

Called telling my computer needed to be fixed.  Have always just hung up before but felt like playing today.  Told him I found it fascinating that he called saying I had a computer that had problems.  He said I was a registered Microsoft user...and I said I found that fascinating.  Then he asked me if I had a computer and I said that he was the authority that called me saying I did...I asked if he knew where I could find it,
and then hung up.

I just got a call from 508 257 4621 (reves stamtis) about my computer. I told him I did not have a computer. He said no laptop or anything. I said no and he said ok and hung up.  I will monitor if they call again.
