Not getting assistance in the closure of all my bank accounts (in branch and call centre

Went to FNB Jacaranda to close my credit card account, savings account, cheque account and personal loan account. I was in the queue for more than an hour only for the lady to place me on the call center which took another hour and every person on the line refers me to another person because they cant help me... I went to the Gezina branch to see if they maybe can assist me but the teller was extremely rude to me and stated that the person who closes accounts has already left for the day, the bank trading hours states they are open from 08:00 to 17:00 Monday to Friday. I logged a complaint online and a gentleman named Patrick phoned me the next day, he requested I put everything on email and so I did. He phoned me stating that he will arrange everything and I need not worry. Not getting any feedback from him I send him a sms to request feedback to which he stated he contacted their debt review department and he is awaiting feedback. I has been 2 weeks and he is not receiving feedback and had to log an internal complaint so that they can assist him. This is the worst service ever!! I just want to close my accounts and be free of FNB's bad service which I pay for!!!
