HELL headquarters surely must be at cell c

I've been trying to cancel one of my contracts since Friday. First there was an error, and then suddenly we couldn't dial through directly even when transferred they said the service did not work and one had to call again later. I called again several times and spoke to the worst call centre agents who insist that you do the same thing over and over and over and over and over and over again. There is no other alterative for a call-back or the ability to send a mail... like it isn't irritating enough that I have to share my number with you 3 times before getting anywhere... Also why do you do you delay cancellation??? Why must I wait till October to give notice, I don't care if you can only cancel the contract at the end of the term but surely you can taker the notice at any time, hate that I am stuck with this horror of a business
