Cancelling my gym membership

I have called in, in Feb trying to cancel my contract and I was advised that I need to let the Feb Debit order go through which I agreed to but in March you guys still debited me and in April. I called in but all I get is excuses so I reversed the debit orders knowing I will get your attention which I did. Instead of doing what I asked you guys to do you telling me I owe. How do I owe you when I asked for this to be cancelled in Feb already. I have an email from Mathapelo Lekoe regarding payment. I told her I will writing a review and unfortunately her name will be on my review. I have asked her to assist and I have not heard anything from her since. Please cancel that contract now.
