*********** Staff, unauthorised Debit Order

There's nothing I despice like cancelling an insurance with but still proceed to debit even after I have cancelled. To begin with I lodged a complaint and one of your staff Gugulethu Temba sent me an email assuring me that it has been cancelled this was on the 30/12/2024, but I then notice on my app that its still active(meaning she **** to me , to dismiss my query)how ***********, So I took it upon myself to have it cancelled. But yall still went ahead and tried debiting and the debit order was unsuccessful, Can Please SBSA explain to me who liable to pay that unsuccesful payment fee, Can This be resolved as soon as possible before I escalate it futher. And I hope I will be charged an Overdraft service, for having my account on a negative balance
