Greedy, Desperate and Uncaring

I've been a client with Vodacom for years however lately their agents are becoming more greedy and desperate for sales they tell you one thing and do another. I have been following up on a recent upgrades I did I was told a different value comes payment date a different amount was debited. I reached out for assistance dololo I always get the same response we will escalate to the back office after listening to the recording we will get back to you however nobody ever does and when I wanted to cancel they tell me I will have to pay more than R29 000, now I will have to suffer for a whole 3 years.
