Vodacom, biggest *****s in SA

Two incidents of *****ulent behavior: 1. Agent called me and upgraded my cellphone contracts to more expensive contracts by lying that they were doing it for free on the basis of sms allocations that I wasn't using. 2. I wanted to cancel a data contract. They offered me a deal to retain the contract that never materialised. When I tried to cancel the new contract they tie me up in a sea of contact centre agents that are clueless. Vodacom is a *****ulent corporate with no regard for it's clients. How are they allowed to continue trading like this?
