CELL C DON'T CARE

I never thought I'd say this but looks like cell c is becoming the worst network provider in South-Africa. I complained on their Website, They phoned me and admitted they have a problem and will not fix it, I complained here the phoned me they said they know they have a problem they will not fix it I must just cancel. Now everywhere we go we're experiencing Cell c signal problems Now seeing that it is so easy for Cell c to tell me they will not fix the problem and I can just cancel, I would like to cancel all 7 my contracts as I feel Cell is not moving forward and don't about their clients anymore
