Signed up with TPS but still getting them. I try to be polite to cold callers but over the years I have had them:
slam down the receiver rudely on me (happens at least once a week, even with supposedly reputable firms)
try to con me/hack my computer
not give their name/company first (this is surprisingly common even among non-scammers)
refuse to give their name/company at all
be rude about my financial situations (yes you guessed it, charity chuggers)
keep arguing back when I explain I am not interested
give misleading information about the company/product
calling repeatedly after I have said I am not interested (who wants 3 calls about double-glazing from the same company in one week after you have explained that all your windows are already double-glazed?)
most of them start with an outright lie: this is not a sales call (we are not just talking scammers here, but supposedly reputable firms)
Since I sometimes work from home, every cold call represents a potential loss of income for me, and as I have poorly relatives in various parts of the world I dare not leave calls unanswered.
How would these cold callers react if their income was affected by people insisting on calling them at their call desk and not taking no for an answer? And then ringing up again? And again? Judging by how they react when I politely tell them I am not interested- probably very rudely.
