PLEASE ANSWER ME

I've been trying to get hold of anything/anyone in order to assist me in updating my banking details for me to be able to pay my account. There are no clear instructions either on the website or app. I've tried contacting multiple helplines but only get's redirected to an irrelevant line. I understand that it's difficult during lockdown but this is a valid question that's supposed to be listed in your FAQ's. Even Tobi could not help me. This is extremely frustrating because Vodacom is always quick to call when you are late with a payment - I want to avoid being harassed by them again.
