Debit order on date not agreed upon

ABSA bank sent me a message on the 14th of December informing me that my account will be debited on the 15th. This debit normally goes through on my account on the 20th. I was in agreement with ABSA that my debit order must go through on the 20th because that is my salary date. I went to the branch (Woodbridge Square in Glen Marais) to fix it and inform them that they should not debit my account on the 15th. I was assisted by a consultant by the name of Ayanda who called the department that was supposed to help me. The consultant I spoke to over the phone could not help me and she hung up before we were even done. The consultant at the branch , phoned again and the new consultant assured me that the debit order will not go through because they were referring to customers who receive their salary on the 15th of each month.

My account was debited today. I need that money to do other things and now I am unable to do those important things because of their error. I have not yet received my salary and this is an inconvenience.

I drove all the way to the branch to resolve the matter and was assured that I will be ok. I am really disappointed in the service I received at ABSA.
