Unable to cancel my contract

If you know what I know you will never consider to become a Cell C client. I phoned Cell C to cancel one of my contracts on 20 January and they said I have to pay for a full month's notice, but my service will be terminated in 30 days, so on 20 February. Unable to verbalise my disgust about this unfairness I raised my voice - AND THE AGENT PUT THE PHONE DOWN IN MY EAR - and worst of all did not action the cancellation. I feel sorry for those people at Cell C who care about their customers (if there are any left) when they are going to loose their jobs when Cell C goes bankrupt - beacause I cannot see how they can stay in business with this kind of service. For the agent who didn't help me, don't sweat - Cell C management doesn't listen to those "recordings to improve their service". You will just be on the street without a job one of these days!
