When people pay for a service Cell C cant provide..

Cell C

I Pay A monthly fee for a service you cannot provide, I have Bad reception at home and at work I have been battling with your call centers for almost 7 months, in my contract I get 5000 mins talk time ill be lucky if I'm able to use 500mins, as for data to use it I have to use the roaming option on the Vodacom network and this is only in certain areas others I have to change it back just to make a call and have found by using this option I'm only able to use 5 gig, your customer service has sent out a technician because its so bad and his exact reply was this is the worst signal he has ever seen (on the unit testing the signal which he gladly showed me) and had just been to do a test on a client 2 roads from where I stay and had the same problem.. Then I get told sorry there is nothing that can be done and after many many wasted hours on calls to Cell C call centers I was finally told the best cell C can do is cancel my contract from there side, I got a an SD number for the cancelation that was 3 months ago Baring in mind that Cell C are canceling the contract and not me you expect me to pay for the balance of the contract, if that's the case then I want to be refunded all the payments where I have not been able to use the service you advertise but cannot supply. Its like paying for a 2018 BMW but have to use a bicycle to get to work.. I only want what I pay for and you cant even give me a portion of my contract.. I sit with a phone on another service provider 2cm away from my cell c phone and Cell C will have poor or no signal and the other phone works with no problem.... Again after 7 months of HELL YOU(CELL C) still cant do anything makes me think this service provider is a joke I have viewed several complaints with the same problem makes me realize you ARE!!!!
