I just answered a phonecall from this number. I heard a very polite "Good evening, ma'am" in a foreign accent. I said, "Hello! Let me guess -- you are from 'Windows Operating System,' right?? He said, "No, ma'am. Actually, I have the wrong number." Maybe he was one of those who say they are calling from 'Windows'; but perhaps since he was called out on it, he chose to say he had the wrong number instead of giving me his sales pitch; and then perhaps went on to the next person to call.
