I have just had one of "those" calls from Micrsoft Vindows
My wife answered the call then handed it off to me.
ME: hello
Them: Hello am I speaking to Mr (MY name)
ME: Yes
Them: My name is Edvard and I am calling from Microsoft Vindows about a problem you are having with Microsoft Vindows
ME: (enthusiastically) Yes, which one.
Them: the computer running Microsoft Vindows 7
ME: (enthusiastically, again) Yes, which one.
Them: The one with Microsoft Vindows 7
ME: (enthusiastically, again!) Yes!, which one.
Them: how many computers do you have there with Microsoft Vindows ?
ME: 6
Them: OHH!
ME: give me the registration number and I will get the machine
Them: Prolonged silence
ME: They didnt teach you THAT in class did the you dick head!
I hang up and said to the wife "that was fun"
I could actually hear this dick reading the next question to my responses, then as I got more agreeable the pauses between questions got longer as he scanned the "next question" list, then after the registration question from me the was a deafening silence.
I did for a moment consider telling him we were on the do not call list but decided to have a bit of fun instead
I can not believe they are so stupid to think that there is anyone left who would still fall for this scam
The first real give away is the accent.
