SO CALLED GLITCH!!! NOW I AM LEFT WITH ADDED DEBT!!

I refer to the following reference number phindile*** I am very disappointed and stressed by Standard Bank, On the 22 May 2023 I increased my limit on my RCP and accepted the debit order mandate on my Banking App. Standard Bank normally debits my account on my pay day and when I looked my account was not debited. I then thought that they would most probably only debit my account the following month because my increase was so close to pay day. Nevertheless I was still cautious and waited to see if they will debit me at the very end of the month. This did not happen and I was now convinced that I will be debited at the end of June 2023. I received a sms on the 04.06.2023 to advise me that I am now in arrears with my RCP because of non payment. I proceeded to call Standard Bank on 07.06.2023 and they advise me that there was a glitch in the system and I must make a deposit of R2.3K or it will accumulate interest. I do not have the 2.3k to pay and frankly this is very unfair on me as it was a mistake made by Standard Bank and they only picked up their mistake 11 days later. I am in a very difficult financial situation of which Standard Bank is fully aware of. Why must I now commit to paying R300 which I just cannot afford or any amount towards the "Arrears" which was NOT MY FAULT!!!!! Standard Bank has now put me in a terrible financial dilemma on top of my current Financial situation. I think its unfair and quite pathetic how they handled this so called "GLITCH" Highly Stressed!!
