We have gotten all of the calls but the most memorable was the Microsoft one; after listening to the spiel I very nicely said "no you aren't from the technical department; this is a scam and I'm not going to be a victim." Immediately the person started screaming "M..... F....." repeatedly so I told him -"that was great - glad I got it all on tape for the SEC" and hung up. That ended those calls for at least 6 months...
