I also think rude and unprofessional is ignoring regulatory lists for non-contact for marketing, ignoring data protection laws (buying stolen data, using for purposes other than permission has been attained for, illegally selling data), ignoring the person called when they say they are not interested and repeatedly calling after both explicitly stating disinterest and requesting non-contact.
When you have tried to be polite in the face of all this what recourse is left?
To be honest, I have been cold called so many times, by so many people, representing so many organisations that AFTER trying to not waste either party's time the only protest I have left is to make the practice too expensive to be worthwhile.
I would, however, be open to trying other solutions to stop unnecessary calls (changing my phone numbers or not having them are not valid options). I am open to suggestions.
