Surprise extension of Contract terms.

Once again I have to resort to Hellopeter and social media to get an answer from Vodacom. Customer service is absolutely **********. I upgraded two of my lines a while back. Afterwards found out that they were extended as 3 year contracts. I would NEVER have agreed to the price of the package if I'd known that. This was never communicated to me by the agent calling with the upgrades. I've phoned customer care to ask for a recording of the conversation. I was promised a response by the agent but never received any reply. Lately it feels like all transactions I have with Vodacom blow up in my face and I'm just completely fed up with everything. Takes weeks of struggling to solve any issues and causes a lot of unnecessary tension.
