The C in Cell-C stands for con

I'm honestly so fed up with Cell C. I called Cell C on the 24th of January to cancel their 'Getmore' service, less than a week after it was activated. It's mid-May and I'm still paying for it, still being transferred from pillar to post, still waiting for a call from the 'cancelation department'. This is just unacceptable. I can't afford to pay a cent more than I intended because I'm a full-time student and I'm completely dependant on my bursary. I canceled it because I can't afford it and I expect a refund for any payment that was claimed after I called to cancel- in light of the 30-day cancelation period!
