My advice, always hang up on a nuisance caller, it ruins their game. If a phone has caller id and the number is foreign, simply don't answer it.

Telemarketers are a pain in the neck, after my dad died, they kept calling me and asking if they could speak to him. In the end I'd put the receiver down, it's because I transferred this number from my previous address to my new address

They just don't get the message they ring and ring but never on weekends. I shouldn't have to change my number to stop these serial pests from calling. Bloody nuisance!!!

This is the 3rd time I'm complaining about scammers & telemarketers calling me up for no reason, I'm about to take legal action with my solicitor if these harassing call's keep reoccurring, this is very serious and I want these serial pests to leave me alone and get a life, I'm over this nonsense.
