Pathetic Service

I went to Nedbank inside Killarney Mall to do some IMPORTANT banking. The guy that needed to authorise what I was trying to have done WOULD NOT assist. Instead, he was on the phone for a full 20mins, WASTING MY TIME!!! Disgusting service. NO apology, NO acknowledgement of the error on his part and above and beyond that, I DID NOT EVEN GET TO DO WHAT I SET OUT TO DO TO BEGIN WITH! I am furious. DISGUSTING SERVICE!!!
