Absa slowness & incompetency

The way ABSA is so slow & *********** compared to FNB. It make me so sad. Since Monday I have been trying to change my debit order bank details with no luck. Every time, I sent the form, I'm told to change this. Its like they don't know what needs to be done. So when will the debit order be effected then as its sickening now? Also, I asked them to add the home loan account on my absa personal profile but i wasnt helped on that,why?
