charged more money to cancell my contract

I called the call centre in December to request settlement amounts for two of my contracts.i paid the money that I was given and called in to request cancellation.both contracts were cancelled, two months later there was a debit for r498 on my account, when I enquired what it was for I was told it's the cancellation fee. I was never told about any cancellation fees,i was only told about the settlement amount which I paid. I logged a query ref no ***. & *** and I am still waiting for the voice records where one of your consultants advised me that there will be a cancellation fee. Feedback on the query has been outstanding now for 2 months as it seems like nobody is keen to resolve my query.i have been with cellc for four years now and I have never experienced this kind of service.i am extremely Dissapointed.
