UNAUTHORISED PAYMENT - RCCS JOURNAL

Yesterday another unauthorized payment went off my account. No sms, no phone call, nothing. I logged into my banking app and saw that a payment had gone off my account. The reference number was "Journal Debit". I tried phoning the bank yesterday and had no luck resolving anything. Last year they did the same thing to me at which they said I was in arears of one month's payment on my personal loan and they just deducted an amount. I explained that I had a loss of income and then I arranged a payment plan with them. Absa did not deduct the money as arranged which still showed that I was in arrears. In January I found a new job and every debit order was successful. A lady even called me in Feb and explained that all was well. Now yesterday they deducted their own amount from my account, leaving me with R300 left. I only get paid next and I have a 7 year old son. Is this even legal?? I don't have any other financial support and I still have 6 days until pay day. This bank has caused me nothing but stress. On Wednesday I opened up a ***** case because someone was able to clone my card details and now this. STAY FAR AWAY FROM ABSA!! I am going to seek legal advice regarding this matter, there is a child involved for goodness sakes!!
