This scam has been going on for a long time. I have a few different responses to them, depending on my mood. Once, I said : "Thank God, you've called back. I filed a request for assistance with Microsoft almost an hour ago!" That got them excited - but what came next really got them wound up. I said I was filling in for the regular IT guy who was on vacation, and all the servers were having problems, Here is where they really got excited and brought another guy on line who spoke better English - I told them the bank needed to open in a couple hours! They started telling me what to type, and I'd ask them to repeat it, with me, repeating each letter, slowly back to them, and getting it wrong, every few letters. They really thought they were going to hack a bank. After a few minutes, I hung up.
Another time, I had one screaming obscenities at me. As he started his spiel, I stopped him and said: "I know you are a scammer and are trying to steal from me. As we are talking, I hope some :cus:, just like you is on the phone with your mother, stealing all her money." He went nuts and went off on me - I was laughing as I hung up.
I really hate thieves - I wish there was a way to stop these :cus:.
