Poor service

Hi. I write this with serious concern and disappointment from your service team. I have 2 credit facilities with African Bank. The month of February 2025 I called in and requested my debit order date to he changed from the 20th to the 31st of every month and my bank be changed also. The lady assisting me told me that in order to change banks I need to send bank statements and ID, but she can only change the debit order date, on which she did. The deduction for my facilities in March 2025 happened on the 31st as requested. But this month I got a notification stating the deduction will happen on the 17th!!!!! I never agreed to the 17th!!! I called in and spoke to someone, she is now stating that the change was not done due to the fact that I didn't send documents. I told her the previous lady only spoke about the bank change NOT the debit order. She tried to cover up with lies and was not even listening to my request trying to prove her point to cover her colleague. I insisted to speak to her supervisor, I eventually did. She said to me it was done only for the 31st, question is how so ??? What kind of system that does things temporarily??? Now deduction went off on the 17th and no money was in my account which will affect my credit score!!! The supervisor said she will sort the date issue out and requested my documents which sent to her via email. She NEVER got back to me, I NEVER got any updated debit order date amended. Is this the kind of service we are offered??? I will take this up further because clearly your services are not up to standard. I want my debit orders to be moved according to my salary date on the 25th of every month!!! My number is *** , email address ***. I want this changes done
