Cancellations *********** Staff

I called Cell C for a settlement amount to have my contract cancelled, I paid the settlement amount in 3 days. A few days later a debit order went off my account for the same contract. I phoned to get my refund as I have paid the settlement amount already. I was then told that the debit order that went off my account was for the device. Why do I need to take the fall for the information I was given by one of Cell Cs *********** staff. I then phoned again to request a refund and was told that a manager will call me back, I never received the call. A few days later I called again and demanded to speak to the manager but was told they are in a meeting and the agent I spoke to advised that he will have a case opened and will phone me to give me the case number, I still haven’t had from Cell C again. I just want my contract cancelled and since I paid the settlement I demand a refund for the debit order that went of my account immediately.
