Poor customer service

I've recently changed jobs and as a result my pay date was changed from the 25th to the 27th, pretty much all of my debit orders go off on the 25th and I needed to find out how to change the date. I emailed info@fnb and received a response that I needed to provide more detail as to the debit order, date, amount and reference number as well as my ID/Account number which I went about compiling only to receive another response saying that I need to contact the companies directly to change it. Which is all fine, but obviously someone didn't bother to look at the email because 3 of the debit orders were from FNB ( Homeloan and 2 for FNB connect), I sent another query to ask how do I then change the FNB ones, to which I receive a generic response on how to STOP a debit order, I don't need to STOP it I need to change the debit order date, but at this point I am quite frustrated because it's obvious that no one is actually reading the emails so it's quite pointless to response again. Furthermore, what is the point of having the titles of premier bankers, when it seems like they can't even assist in such things? Do I have to upgrade to get better service, or if this is the pathetic service in general then I should just downgrade because apparently there isn't any assistance anyway.
