Debit check plain ***** and these mysterious automated processes also scary. Now we are not secured in ABSA banking

Debit orders for small amounts and large amounts are being debited. When I went to reverse the debit orders I was told I can’t I must ask the service provider to reverse. Shocked I have not done a debit check on these yet they say it was done how I don’t know but they refused to help me. And these *****ulent amounts are both on the Chequers and credit card. So more than a thousand is missing and I am supposed to survive and trust the bank? One month one of these debit orders caused a R150 charge because my account didn’t have enough money
