Debit Order Date Change

Good Day<br> I would like to complain about Capitec Bank, I have an existing debit order that goes off too early every month. I have been to two branches regarding this as I am incurring unwanted charges and thus getting a BAD Credit record regarding this.Apparently on the system my Salary date is determined to be the 29th of every month, I had proved that it is not the case as some months as my salary gets put into my account sometimes a day or two later. I have showed them bank statements as well where they can clearly see that it is after the 29th, I have even contacted the client Care Centre , the 31st of August already and they advised me that someone would call me or sort it out. I don't understand how a simple debit order date change can be so impossible to do? I am so disgusted at their customer service and how they can not change a simple date so that both parties can be happy.
