Vodacom Arrogance

Took out a contract @ R148 pm for 3GB data pm. After 3 months of fixing and reloading it suddenly worked for 1 month but the next month I was billed for R299 pm. Their answer was, after several phone calls and e-mails, ... Sorry the R148 pm package is no longer available. There was no notifications of this change and they feel their actions are perfectly acceptable. I am still fighting and even requested to be transferred to an acceptable current package - -they are sticking to their R299 pm which I never accepted. I have no choice but to ditch Vodacom.
