Contract activated not the one I agreed to

I spoke to someone in the Cell C Direct Call Centre yesterday. I was looking for 2 contracts with Samsung J1 handsets on the straight up 50 contract. The Cell C agent told me that the price is R99 pm per contract but if I agree to add R10 per month, I would then be able to top up some airtime if my R50 or 50MB data runs out. The cost would then be R109 per contract pm. I fully agreed to all the terms and conditions and they recorded the conversation. <br> I received emails confirming the order but the amounts were then changed to R129 pm. I submitted a query via email and they phoned me back saying that this offer from yesterday has expired and is not valid today. They listened to the phone recording between myself and the call centre agent and confirmed that I did in fact agree to only R109 pm per contract and would then receive the J1 but if I want this, they have to change the handset. I lost my patience with the person I was talking to and was really rude to him, but they can't go around changing contracts and expect people to just accept it. They are not honoring the contract we agreed to yesterday. And this is how Cell C treats a loyal customer of roughly 13 years...
