Refund issue

I cancelled a policy with clientele within 24 hours and the debit order was R333. When the money was refunded i only got R290. Bare in mind i kept being charged by my bank because clientele was still running a debit order through my bank. I reported the issue but clientele toke thier time to stop the debit order. I had to always reject the debit order from my side which probably resulted in me being charged. Now i sent an email about their refund policy and there is still no reply. I want the outstanding amount from the R290 i got. This is only because I kept being charged for something I already cancelled. It is like being charged for a cancelled monthly subscribtion. It just doesnt make sense to me.
