FNB think they can decide when debit orders can go off! watch out

I received an sms stating that my student loan premium will be deducted on my salary date rather than the end of the month. This I don't have a problem with, BUT FNB decided that my salary will be in my account on the 12th. They forgot to inform my employer to pay my salary in on the 12th (notice my sarcasm please). Now I only receive my salary on the 24th, which means my account went in overdraft (which I will be charged for). This is a very convenient way for FNB to ensure they get a bonusses before Xmas
