Vodacom Disingenuous Contract increase

I have received an sms informing me that the costs on my Vodacom 24 month contract will be increased.<br> <br> I feel it is disingenuous to increase these costs without giving me the option to cancel my contract at the same time.<br> <br> I was under the impression that the 24 month contract costs were fixed costs, as nobody sane would sign a contract allowing a third party to lock them into any amount they feel - this kind of contract is one-sided.<br> <br> I cannot be expected to read through all the fine print in their contracts - and I feel that a precedent has been set by these kinds of increases never having been summarily been imposed before to my knowledge?<br> <br> If you want to increase the cost of my contract, it is only fair to give me the option to opt out.<br> <br> <br>
