Stop apologizing and give back the money

On 16 July, I requested a 1Gb data bundle. It was loaded on my account 3 times, so I was charged R450 and allocated 3Gb in stead of R150 and 1Gb. I phoned customer care, used the online chat and complained here on Hello Peter, but the only response I got was that someone will phone me after the next billing run on 04 Aug, since there was nothing they could do in the current billing month. This sounds like royal brown BS to me, but fine - we can wait two weeks. However, by the 7th of Aug, I had heard nothing and was getting agitated again, so I complained to customer care, sent emails, etc. - until now, nothing. Not a call, not an email, nothing. There was one flimsy email response before the 7th, which said someone will contact me soon with a copy-and-paste apology, but that was ages ago and the issue still exists. In the meantime I received a bill of more than R1000 because of this and not a hint of actual support from Vodacom to actually get it fixed. In the meantime, I am swimming in data, which is about to expire, since the 30 days are almost up. Vodacom has really gone down the tubes lately. Very disappointed.
