Cell C is the pits!

I’m annoyed that it has to take countless calls to cancel my contract with cell C. I went and requested a settling amount which I had to pay to cancel one of my contracts. I received it and was told to call the retentions department 24-48 hours after I’ve deposited the money, which I did. The lady that I spoke to said someone will call me to proceed with my cancellation after confirmation that they received the money and also tells me that the debit order will still go off for that month. Few days later I call again to find out what’s going on and I hear that the money I paid was actually allocated to a credit account which will go towards my installment and there’s no such thing as someone calling me to cancel my contract. I immediately ask the lady to move the funds from the credit and allocate them towards my contract cancellation, she says she did that and sends an sms confirming my cancellation date. The debit date comes and it doesn’t go off, I call, I hear that the money was never allocated to my cancellation and it was used to pay the debit order for that month instead. Now what must happen to the money I initially paid to cancel my contract if some of it has paid my installment? All I want it to cancel my contract, allocate the deposit I made towards canceling my damn contract! I’m really tired of asking for the same thing and they keep saying it is done but clearly it’s not. And don’t reply to this review and say someone will contact me and when they do, they still don’t do their job at the end of the day.
