Non-existent service, *********** technical dept.

I have had a data contract that I use in my normal phone for years now. Suddenly about a month ago I can't load any once off data anymore. Not the app, their website or *111# options want to work. All I get is either the monthly recurring option, or a message that tells me that option is not available. I phoned Vodacom about 3 weeks ago, after which my case was handed over to tech support. They would get back to me. A few days later I get an SMS that the case has been closed. No other info, nothing, but my issue still hasn't been resolved. What did happen was that they deregistered my account, so I needed to create a new account. I phoned them again, yet again my case was sent over to technical, and they would contact me. A week later I had to phone again, same thing, tech support will get back to me. This is now another week later, I have not received a single phonecall from Vodacom at all. Everytime I have to talk to someone that doesn't have a clue, and those that are suppose to have a clue are never available and probably just sits on their rears doing nothing, not giving a damn. Non existent service. My issue still hasn't been resolved.
