Vodacom a bunch of *******

Today at 12:25 i checked to see what was my balance on my Vodacom account only to be supersized to see that all my balances are 0, 0 Data, 0 Talk Time, how is this possible, as the day before i still had over 400 min talk time and over a gig data. I did not even use my min during the day. When i called them to check what is going on the customer care (as if they actually care) said that it is due to the move to a new contract, so when i asked why he said must be a mistake, but already i have used my phone to call and used data during the day and already the account is standing at over R100,00 of usage, due to there mistakes, no i ask how can Vodcom just come and ***** all my data and air time which i have already paid for, this makes them in breach of their own contract and makes them a bunch of ******* *******, *****ing from their clients without the clients knowledge , Vodacom you are a disgrace and it is not worth being a client of vodacom.
