Yes you have two choices - either hang up on them or, if you have the time, act the daft idiot and string them along
I let them into Ubuntu once in VM after stringing them along for about 20 minutes on the phone, " oh wow " I said " My pc is acting strangely and it is slow, What's that you say? You scanned my PC and found all these errors? And I could be hacked? Can you please help me fix this? " They went on to explain how Microsoft looks after its customers and that I qualify for some VIP plan costing $299 AUD, For that they would remote access my PC on a regular basis to run updates and fix any issues. I was so exited that finally somebody was going to help me with this electronic gizmo, where do I sign up?
That is good says the rep," Is your PC on now?" I I replies with Yes. Good sir first thing I need is an email address so I can send some software that needs to be installed so I can log into your PC, Then I will run some tests and show you where the viruses and corrupt files are. For the next 10 or so minutes I messed around with not knowing how to download an attachment, When I did download it I couldn't run it because nothing happens when I click it, Then he explained to me the file was zipped and how to unzip it using win rar, I really didn't get it all so the guy kindly sent me an unzipped copy of Team viewer. Then we had to go thru the process of giving him the log in numbers, Being an old short sighted man with the wrong glasses I messed up giving him the right log in several times, All the while saying " sorry for wasting your time because PC's are just hard and I don’t understand all this jargon "
The lovely man at Microsoft was so kind understanding and patient with me, Constantly reassuring me that its OK he deals with new PC users everyday and totally understands my situation, He was so consoling and trying to explain things to me in simple terms that it took him over 2 minutes to realise that he was not looking at a Windows Operating system, That's when he became shall we say rather upset with me, and hung up.
