The worst Service Ever

I had the worst experience ever since I've been a Fnb customer, I called in to be to be assisted with a debit that didn't go threw, Firstly the consulted that answered the phone kept quiet, I heard to greet and keep the conversation, he did bother to ask how he can or tell me his name. When he finally he said something he told me that his system is frozen and I must call after 10 mins, I asked why can't he call me back as his system is off, than he put the phone down on me... I mean if you guys don't want my service please assist with closing my Fnb account
