Regular occurrence of unauthorized debits

While I am generally happy with Capitec, what concerns me very much is that I have just had an unauthorized debit on my account for R99. This is very concerning as 6 months ago I had to close my original Capitec account and open a new account due to the same thing happening. I had only had my original Capitec account for roughly 6 months when it happened the first time. I can't keep closing my account every 6 months due to unauthorized debits appearing on my account. There appears to be a a serious security breach. Please could someone investigate and implement better security measures. I see I am not the only one experiencing this problem.
