Useless Bank monies are just being deducted without authorization

I stopped a debit order with Capitec bank. I cancelled a contract with a tracking company and I personally went to the bank to stop the debit order. For the past 7months, this tracking company has been taking money every month and I get charged by capitec on a monthly basis for disputing and reversal as well as charges for the same debit order which they **** to me that they had blocked. It looks like they can't block this service provider and the Debicheck facility doesn't work. Highly frustrated. Imagine how much I have lost for all these transactions on a monthly basis. Put your house in order capitec bank or I am now taking my business elsewhere
