The same story for me.   It was early in the morning, I was not fully awake and the same thing happened as described above.   The guy was smooth and had a good quick answer for everything.   Thankfully I clued in before I compromised my computer as well.   You think this will not happen to you because you are much too smart and aware of these schemes.   I felt like an idiot but what a valuable  lesson learned.

Sam Watson - Indian accent - sounds like the same name and voice a few years back with the Microsoft "your computer is compromised" - same thing this morning with the $600 -  told him to #$$&*(^* off,  Should not be considered part of the human race

Just received a call from this individual same scam....same Indian guy.....same [***].....as reported above.  I hung up....really this fellow should be locked up......

Same thing...early 7:10 this morning. .600 wired to India. When he asked for my cc #..I said "I don't think I should be giving that over the phone" and he hung up. I reported it to Visa

I have call display and looked at the number -- 414-742-3949 -- with some bewilderment and then great annoyance.  I was so annoyed I answered it.

"What do you want?" I growled into the phone.

"Mrs. ...?"

[No reply.]

A male voice with a very strong E Indian accent goes on to tell me that they are doing a routine check to see if I had charged $600.oo to my VISA account.

I think I interrupted him loudly with something like "OH! Gimme a break!" and a profound hangup.

One site said the call originated from Elkhorn Minn.  But methinks that's just a transfer hub and the call originates from much further away.  Maybe INDIA, at a guess.   Sounds very similar to the "MicroSoft" guy who called to "fix" my nonexistent computer.  I strung the MS guy along for a bit but I was just NOT in the mood for this nonsense this morning.  I hadn't even had my COFFEE!
