"Hello, we are calling from Microsoft..."

So, a lot of us have gotten the call where someone with an obvious accent claims to work for Microsoft and tells you there's something wrong with your computer. At first I just ignored the calls, but lately they've been using local mobile numbers, and as I'm searching for a job you really don't want to ignore potential employers. I then decided to have some fun, and the last few calls have resulted in me releasing my inner troll. As I suspect they will continue to call me I'm interested in ideas for more trolling. Give suggestions or examples from your own experience!

When I got the call earlier today I pretended to believe them and acted distressed, I then told them I had 97 updates on my computer and that he had to wait. He filled the time with asking different kind of questions, to which I responded as stupidly as I possibly could. 

"What kind of computer do you have?"
"I have a Mac"
"A Mac? Why did you not tell me this?!"
"Oh, does it matter? Isn't Mac and Windows basically the same thing?"
"Yes... of course"

I continued to waste his time while counting down the "updates". When it was almost done I got this question:

"What is your occupation?"
"Oh, I work as an IT-analyst at the Swedish Police. I have just forwarded your location and information to your local police"

And that was the end of that call!
