Is that even legal?

I don't need to write much, everyone know the story, Vodacom is simply increasing the subscription on both my contracts. I emailed them yesterday saying that if I don't hear from them within 24 hours I am reporting this on Hellopeter and I will also seek assistance from the Ombudsman.<br> So,<br> <br> Dear Vodacom<br> With petrol going up astronomically and market conditions as they are, it has become necessary for me to lower my Vodacom subscription. On 1 May 2015 you will only be able to debit my account for a maximum of R 450.00, so that I can still make the calls I need and sms what I need without worrying about costs (which is breach of contract I know, but since you don't seem to honour contracts I thought you won't mind).<br> <br> I would like to thank you for your support (albeit it non existent at times. Point in case, the last 24 hours) and assure you that I will continue to pay what I feel comfortable with (which is why I took out the contract that I did) and not a cent more.<br> <br> For more information on the lowering of my subscription you may contact me.<br> <br> Regards<br> Jacques Prince
