Bad service

I have a loan with Absa of which was taking on the 1st of each month on the 14th of February 2022 I phoned to make a change that it should take on the 20th of every month I have noticed that today 02 of March they have taken it and there was a bounce on yesterday because there was no money on my account. I have been phoning them since 8am this morning, first they did not answer my calls at last the lady took my call, she told me even though the amount has gone it does not appeared on my personal, therefore i must try to reverse it which is going to cost money, otherwise there is nothing she could do1
