Worst Service and Run Around

I was a customer of Vodacom since 1994. I moved to Nashua. In Nov 2014, I purchased multiple data packages not to go out of the bundle. When Nashua accounts moved back to Vodacom, I was charged for those bundles as if out of bundle. Since January 2015, I am trying to resolve the dispute and while talking to collections an agent said that data department was willing to give me 50% of the data costs. In the meanwhile, the automated system deleted me of the network. I have been for only today sent between collections and data no less than 8 times. Data claim they cannot assist me and collections refer me back to data. The processes at Vodacom is seriously flawed and I have to pay for services not rendered. Vodacom has the worst customer service I ever encountered and nobody takes ownership for problems at all.
