Breech of agreement

I recently upgraded with you guys. After I wanted to cancel. I was swayed to stay by your cancelation/retention department. I talked to Pindile, who assured me the call is being recorded so you can listen to it.

After she said the amount, I must pay, I asked her about a yearly increase. And she assured me the amount I signed for is the amount I will pay for the 36 months of my contract. And now this weekend I get a SMS stating my premium is getting increased.

I'm no lawyer, but what she did was false and misleading representation. Be it intentional or not, it is for you to determine. But it's on recording that she said I will pay the amount I signed up for for 36 months.

How do we go to work to ensure I will not be billed additionally?
