Terrible service

I am very anoid and dissapointed at how my account is being handled while reaching the end of my contract. The are adding an additional R800 and you will actually cry if you hear what explantion Sifiso Mochitsoe is giving me as a client i have a two year contract i all my discounts must be for two years until i reach the end of my contract by Cell C doing what they are doing I believe that is a bridge of their contract I cant express my disgust in the way they are handling their clients
