Protecting your parents from scam & spam will matter a lot in the future. I've trained my mother on erring on the side of not believing whatever the email or person on the phone says and calling me to verify. It works great, she'll happily take a note from them e.g. when her mobile provider (or someone claiming to be her provider...) calls and asks how I can reach them. The legit calls will be happy to provide a callback number, and the other ones will give up when she's persistent that she can't help them. They'll move on to easier victims. The cost cutting can be immense as you mentioned. Plenty of people have ancient contracts that they never changed.
