Complaint

Visited an FNB branch in Pier 14 to do a deposit at the ATM. Before transaction was finished ATM switched off. A consultant by the name of nwabisa came out and started shouting as to why I was holding the queue when I tried to explain my situation she just asked me to move and said there was nothing she can do about it. Upon entering the branch I was advised to fill in a form as it would take 48 hours for the deposit to appear on the account. When I spoke to the manager his name Mzuvukile who was on his way out he advised me to lodge a complaint as there was nothing he could do to assist me. Now what do I do on this situation because the money is deposited for a person who is sitting and waiting for that money and now both we are inconvenienced and with no assistance from any party in the branch.
