Vodacom cant resolve ***** on data card

Its been over 4 months since i informed Vodacom that a datacard that i requested to be blocked because of theft was not blocked and was in used for a month after the request to block the card. This has been taken up by the Vodacoms ***** department and i have not received any feedback from them in the last 4 months. The problem now is that i will not pay for the amount of data used during that month the card was supposed to be blocked and as per the ***** department they also told me i don't have to pay for the outstanding amount. Now every second day Vodacom accounts phones me and ask for the outstanding amount or they suspend my normal cellphone card. I have to explain this every dam day to someone in accounts.. I have requested so many times to be helped but all that accounts say its a data problem and that data department say its *****. <br> So WHO can sort this out form me ???<br> IS THERE SOMEONE IN VODACOM THAT KNOWS WHAT THEY ARE DOING BECAUSE IT CLEARLY DOES NOT LOOK LIKE IT.
