4 months for a query to be resolved!!!

This started on 31 November 2014, where I walked into the Cradlestone Mall store to cancel my 2 voice contracts. I was assured by the consultant that if I paid the settlement amounts in the first week in December, that my minutes, data and smses would be reversed for December, and that this would be my last payment due to Cell C. After making the payments within this timeframe, I was not charged in December, so all was well, or so I thought...<br> In January, I received an invoice for my full normal contract. I called the store and was assured that it would be resolved and if the debit order came off at the end of January, that this would be reversed... DIDN'T HAPPEN!<br> I again phoned the store at the end of January when the debit order came off and was told that the manager had left but that my query would be resolved and I would be contacted. MORE LIES!<br> I then called cancellations directly on 17/02 and spoke to Adrian Burds, who told me that my contract had not been cancelled, but that he had cancelled it the same day. I then called again on 09/03 and my contracts were cancelled, but no still no refund. It is now 1 April and my query is still not resolved!! SURELY THIS IS UNACCEPTABLE?
