Telkom mobile account details

Absolutely ridiculous rules . Upgraded my bank account so the old one was closed and a new one created . The first thing is there is no clear way to submit new banking details. Not the app ,not the website ,not the help line .

What's more frustrating is when you give them the new banking details ,they advise it has to be open for 3 months . What ridiculous hair brain rule is that. Non the less . I'll take my business to someone who doesn't inconveniences theirs clients .
