Yabu.
Although if It's the call centre of a company that I actually deal with I am always polite and nice and wish them well.
However.
I have done everything humanly possible to lessen the likelihood of any form of uninvited communication, from tps to "no cold calling" signs. I do not, however, have caller display as I don't get on with those newfangled phones, and, you know, because a few businesses think they are so fucking entitled, why should I?
Despite all this, I get plagued. Doorsteppers get a chilly smile and have the prominent sign pointed out to them. Despite this they will demand to know WHY I don't want their shitty broadband. "because I would touch it with yours and have already reported your company to
otello twice. Don't make it a third."
As UK companies generally abide by tps, and as I've dobbed in the surveys, any cold calls are likely to be scams. I do not like being called at 9pm by some arse from Microsoft (not). My initial terror that a family member has died (because no good call ever came at that time) is replaced with cold anger that some fucker is trying to defraud me. So yes. I have tooted my whistle. Not right up close to the phone because I'm not actually heartless, but I do not feel like yet another argument with some criminal who either won't Fuck the Fuck off or keeps my line engaged for aged after I've buggered off.
If I've made every effort to avoid this shit, I have no urge to make nice nice with a bunch of arrogant fuckbastards at best, criminals at worst.
I loathe unwanted communications, and talking on the phone makes me feel sick. Too many vulnerable and elderly people have been conned by cold callers ; I had to see off scammers purporting to be the police "the police don't cold-call, you will now be reported to the real police and trading standards, bye"
WhoCallsMe.com are very useful for reporting purposes. Because the CAB, trading standards and age.uk don't particularly like cold callers either.
