How annoying are nuisance calls? I suppose the clue is in the title!

I find it very tedious, receiving random, unsolicited calls from people claiming;

'You've had an accident' - No, I haven't.

'You're entitled to compensation' - No, I'm not.

'You have debts and want to consolidate them' - No.

'You're entitled to a free smart meter' - No thanks, d

on't want it.

To all of them, PLEASE GO AWAY.

If I want your help, I'll ask.

Rant over.
