No customer service

I went to the Karaglen branch today and I was number 5 in the queue. I want to close my account and cos the tellers are are offline I must come back to the bank cos they can't help. I sat in the queue for 30 minutes and was observing workers come late to work and don't login when they get to their table they make phone calls before login. Only 3 people we helping at customer service and while you got 2 people at the door standing and doing nothing.instead of helping people in the queue already one customer service agent was helping only collections What shocking poor service Worst service ever
