Useless arrogant staff leave me with no line

Two months ago i had an issue with Vodacom billing and my line was deleted off the network. I went into the store at North Gate and was made to fill in a reactivation document, pay in a ridiculous amount of money, which the consultants assured me was correct and will release my contract. At this point i provided updated banking details and this was mailed from the store. I was never informed when my line was reinstated, end of the following month my account was credited, now it is disconnected again as my banking details were not updated. The rude consultant who called said its not her problem, i must just pay!!! I provided the details, vodacom failed to update now i am paying the price, as i will be listed as a slow payer and business mobile number is off again. I refuse to take responsibility for their useless rude staff. I have no issues taking this to the newspapers and even going the legal route. I refuse to go into a store to fix this and waste my day dealing with *****s. Either Vodacom fix this damn issue or i will spread the news through every media channel and avenue that i have access to. I have already sort legal advise
