Cannot load data

<p>I have been battling for almost two weeks to load data on my contract phone. Have done so for the past few years and since the billing system changed, I can purchase data but it does not bill my account and neither does it load. I have made 7 calls to Vodacom 111 and visited two stores. I keep being promised that my problem will be sorted and someone will call me back. I am yet to receive the promised calls. I cannot use anything on my phone that requires data. I have more than one contract on my bill and all other phones can purchase and load data. Just my phone contract does not load. I have had enough of the terrible service from Vodacom!!!</p>
