Vodacom, as a business, is a ****!!!!!

I am a user of Vodacom's airtime advance option. I would reload airtime and then access the advance again. In the passed 2 months there were 2 instances where i loaded R12 and R29 and when i tried for my advance, i still owed them so i could not get the advance. This means that Vodacom is not paying the advance back as i load airtime meaning i end up paying more than i should when i owe them. I loaded R29 on Thursday and i received the SMS confirming this. However, my advance did not top up. When i try call their customer service line (082135), there is no option to talk to a consultant who can explain what is going on.

I feel like Vodacom has made it hard to get ahold of their contact center because they know they are *****ing from people which is exactly what this is. Theft.
