Are you rude to Sales calls?

I certainly am.
They got my number by clandestine means, they invade my privacy and my time…..as far as I’m concerned that gives me the right to be as rude as I like.

I tried polite, they just try and steer you into another method of selling you stuff.
I tried hanging up, but they phone back.
I tried asking for their manager (Because it’s them which should receive the abuse) but they find an excuse not to.
So, I use the best way possible and either go off at 90db with language that would make a Para whinge or just plain insult them. It makes me feel better and that’s all that matters.
We’ve not had any such calls for 11 months now, so maybe it’s worked!
