I haven’t had that type of guy. If I did and had time, I might have some fun with him. Is it the same actual person calling back? Does he acknowledge he has called before, or is it like he doesn’t realize he’s called you multiple times?
There are so many things that can be done, depending on what result you want. Things I have done to spam phone callers in the past include:
* Politely say “no thanks”.
* Hang up on them.
* Tell them to take me off their list.
* Tell them to put me on their do not call list.
* Tell them there is no way I will ever ever ever be interested in their product.
* Tell them exactly what I think about their business.
* Pretending I am interested and going along, but making up information and seeing how much of their time I can waste, or what I can get them to say.
* Speak other foreign languages to them, that they don’t know.
* Invent alien languages to speak to them.
* Roleplay a mental illness.
* Roleplay a fun or weird character.
* Forward their call to various businesses or government numbers.
* Pretend I want to buy whatever they are selling, but be so slow and incompetent about it that they eventually get fed up and hang up on me.
* Talk to them about something I feel like talking about.
* Tell them I’ve told them before to put me on their do not call list, and request more information so I can detail it for the log I am keeping for my lawyer.
* Ask for permission to record the call.
* Tell them that the call is being recorded.
* Put them up to one of the recordings on YouTube that is a “please hold” recording for telemarketers, that gets more and more hostile. “Your telemarketing bullshit is very important to us, so please hold…”
In the case of a “Microsoft support call”, being a computer programmer, I would likely try to figure out what they are trying to get from me, and go along as far as I could to try to get as much information about them and their hi-jinks as I could. I’d make up some disinformation for them. I might also 3-way dial them into an actual Microsoft line… perhaps I should look up an actual number for Microsoft information security. Or a cyber-crime number at some government agency.
I might also ask some computer security type folks if there is a counter-hack to use.
