Vodacom *****s Data and closes disputes no reason

Sm-9mn20-04vm7 - I have had 2 disputes re data with Vodacom since I started scrutinizing my Vodacom bills as they were ridiculous and as consumer I'm tired off coughing up for bad service, poorly trained helpdesk personnel and data I did not use. the first dispute was paid back, the second one, mentioned above has apparently been closed without my knowing. Service... I was not called... the matter is just resolved and I should pay. I think not. I have logged this same dispute again for R900 data in October and want a reply, as I use wifi and my Samsung settings are blocked as prescribed. Vodacom has been my service provider for years... not for long anymore. Service Sucks.
