ZERO customer service

I have been trying to change my debit order banking details for TWO WEEKS!! The customer care number is useless; all it gives you are self-help options & never the opportunity to speak to a human??! I then logged a total of FOUR callbacks via their equally useless website. The mobile app is even worse. I even called a Telkom store inquiring about how I can get in touch with Customer Care, and not even the employee there could assist me! He then ALSO logged a callback for me via the website. I keep getting the SMSes that someone will call me, but I never actually get the call. The bank account that Telkom Mobile has on record is being closed today. I'd really love it if someone who works there could maybe actually do some work & contact me?? P.S: I'm unsure who's in charge of Telkom Mobile's technology & innovation team, but they should probably get fired. Both the website & mobile app are completely NOT user-friendly or even efficient. When it's not hanging or crashing, it's simply useless as far as getting anything done.
