Coverage / Cancellation of Contracts

I have had the worst service in cellphone use history with Cell C. I will recommend to everyone I know not to ever try and use them. I have been struggling with cellphone reception since August 2014. I have been logging calls and queries since October 2015, and no one gets back to me unless I follow up. By end of January 2015 I was told they cannot help me as there is no new upgrades in my home area, Paarl and I just have to accept that. So which means if I am attacked, have an emergency, I have to yell or crawl for help. Even on the road, for most of the time I don't have reception. Then after a long fight, I'm able to cancel the contract, by completing the payment of my handset. All is well, but then! I'm told that the excess airtime of almost R400 and 2 or more GB's of data will go down the drain and will not be carried over when I go to pre-paid! This is ridiculous, unfair and absolute nonsense. How is it that one just need to accept time and go one. Absolutely not good service.
