Vodacom s bad Service

I wrote to Hellopeter a week and half ago regarding the un notified increase i all my contract prices with Vodacom,there was an immediate response that Vodacom will contact me sadly todate no contact .I also phoned there customer services where one has the option to ask that they phone back as all their operators are extremely busy? Its been more than a week and I left two messages again no contact from Vodacom. I subsequently visited the Vodacom franchises where I took out the contracts and in both cases they confirmed that a 24 month contracrts charges should remain fixed??? Obviously the are badly informed and in turn do not inform their clients correctly.The above again highlights the customer servive concern from Vodacom that does not exist.
