Vodacom - Be careful of sales agent call you to renewal your contract.

A Vodacom agent recently phone me with an 24 months upgrade selection. Although we agree to add "100 Minutes" at a discounted rate on my data contract, it was never activated. I have now a 24 months contract with zero minutes. Be careful of Vodacom agents call you to renew your contract. They can't keep their promise. I have now spend multiple days on the phone with there call centres. Vodacom keep on transferring me between retention, activation and renewal call centre agents. I have all the detail of the original sales agent info. Still nobody want to help me.
