Standard bank debt collectors harassing calls.

A missed payment and standard bank keeps calling me every single day and harassing me like Im a ********. They have the nerve to say they will keep calling until they get their money.i know i have to pay extra to get it up to date. Every time i need to repeat my situation and it is stressful. Calling every day is not to change my situation. Why do they have to call like an obsessed ex so many times a day everyday? I really regret ever opening account with standard bank. This is intense harassment and abuse & it will not be tolerated!!!
