No support and incorrect billing

Since saturday the 1st of august i am unable to use my 3 g device. After 4 hours on the phone to their call center which send me from one department to another , i got into my car to visit the vodacom shop to see if they can assist . The repair guy at the shop said that there is nothing wrong with the device and that they have experiencing some technical issues and the data has not been loaded. His words was that the idiots at the call centers will not be able to advise the clients as they are ***********. I only want to use my internet and someone to sort this out. Since the issue has occurred my account is sitting at just over r 500 and i could not even use the internet. Please can someone just assist to sort it out
