Beware: Mtn contracts can be changed at will!

My contract with Mtn is for a package at R209-00 per month X 24. After six months the amount was suddenly increased without notifying me. After numerous efforts to find out what the reason was, I was simply told that the fine print in the contract allows for Mtn to increase the contractual amounts at will!<br> This means that the original offer of a package and the subsequent relevant contractual agreement is not worth the paper it was written on!<br> It further implies that monthly amounts can be increased by any margin without the client having any say in the matter, yet still legally responsible for paying moneys not stipulated in the contract.
