Shocking service from ABSA

Vehicle finance at ABSA a nightmare! After back and forth phone calls and emails to change a debit order date in April from 25th to 28th, I received an email in May advising this was now sorted. Well, it's a joke, they didn't debit me in June as per the correspondence and had to make 5 calls just to get correct details where I do a transfer too. I have since made calls after calls to get this resolved. We down another month and still not sorted. But 100% sure this will become my problem when Bill's are not getting paid because ABSA clearly has no clue what to do!! Shocking service that it takes 4 months and not resolved.
