Just got my call from this number. Indian accent and stated he was from Microsoft and my computer reported issues. I told him my PC was fine and he laughed "fine? are you out of your mind?" I asked for his name and he hung up.
Said he was from Microsoft and wanted to talk to the main user of my home computer. You could hear all the other callers in the background talking. This call is Bull and I told him so and hung up. Do not fall for what ever they are trying to sell.
I just got a call from this number. I said hello about 5 times and no one was there. I blocked the caller from future calls. I can do that on my IPhone and that's my favorite feature.
