How do you block someone from calling/messaging you?
Depends on your phone handset.
Option 1) Restrictive dialing :- you can set what phone numbers are allowed in your phone (not all phones do this) and wont block a number restricted call
Option 2) Nuisance Calls :- you will have to contact your service provider and lodge an official complaint to have it blocked at the exchange.
Option 2 is most effective choice but you will need to make an official complaint maybe even with police
Best Option unfortunately for you change your number and only give it to trusted friends with strict conditions of not sharing it
Yes yes it sucks they cause an issue and you suffer etc but yeah life isnt fair
