You didn’t like what you read and responded with abuse and now you are attempting to justify this. I do not think for one second that I matched your criteria.
The main difference is, some people choosing to abuse people for no other reason than that they are doing their job.
They are doing it because it makes them feel better ? Maybe because they think it’s funny ? Maybe because they think they are “better” than a call centre worker so it doesn’t matter if they abuse them.
Who knows why, but the fact is, they can just say “not interested” and hang up.
But they choose not to. And in my opinion, they are behaving like arseholes.
(I am not talking about Scams like credit card fraud or the Microsoft scam. I’m talking about Sales calls etc. mobile networks, UPVC windows, insulation etc.)
