I loathe being cold-called at home. You get up from your comfy position to be propositioned by a foreigner (who can barely speak English) who wants to offer you cash-back on PPI insurance. Drives me mad. I used to be polite. I'm now a demon. I demand to know where they got my number, I tell them they've woken my baby up with the call and I tell them to never, ever phone me again.
Hmmm, I suppose that's quite tame! What do you say?
BTW, even if you register with that hotline number to never get cold calls, it's entirely legal if they call you from foreign call centres. That must be why I get so many foreigners (or computerised messages) calling me at home. Drives me crazy!
