Vodacom - Impossible to talk to, to fix something.

I have raised a query & received an email response with a Ref Number, 2 weeks ago. The email also said its best to follow 1. SMS - the number does not work; 2. Whats app - goes to a useless BOT which said a human will phone me but didn't 3. Web - also the useless BOT. 4. Telephone Numbers - not appropriate for Prepaid 5. App - they don't reply. Overall for such a major organisation ... they are utterly useless.
