Disappointed

This is disappointing, as I have been a loyal customer to you for 3 and a half years with no problems. I contacted Cell C customer service on the 10th of September requesting to cancel my contract. I was told to make a payment of R249.58 to pay off the remaining amount of my device and commitment fees. I was told that as soon as I make that payment my contract will be cancelled. I made the payment of R249.58 on the 11th of September with Ref ***. Monday the 14th of Sept 13:11, I called to confirm whether the payment was received. It was received, and I was told that my contract and number will be cancelled within 24 hours. 16 Sept I received a debit order of R14.59. 16 October a debit order of R264.17 which was my original debit order amount. I then contacted Cell C on the 4th of Nov 14:54 to find out why I still have debit orders going off and one awaiting me on the 16th of Nov. I explained the situation and was told that my contract has not been cancelled on the system. But to cancel I have to make another payment, and debit orders will still be going off for the next month or two. I then requested to speak to a manager or supervisor and was told that they are in a meeting, I was then asked for a number and told that they would contact me as soon as they are available. Today 9 Nov, I am still awaiting a call....
