Worst contract

I am so tired and done with Vodacom. Vodacom keeps on overpricing me on this contract. I am tired and I have been writing reviews here. I am supposed to pay R230 on this contract but now I always get bills that I don't even know where they come from. This contract is so unfair. Is there anywhere that I can get help with this Vodacom. I am still a student and I thought getting this contract was gonna help my life but it's making it worse. Please I need assistance or maybe legal assistance at this point. I always keep on communicate telling them to block additional services but at this point they are no longer fair
