The worst bank ever!!!!!!!!!!!!

I app**** for a credit card with Nedbank. Little did i know that i was shooting myself in the foot. The BIGGEST mistake of my life. I bank with FNB and arrange for my FNB account to be debited on a monthly basis. For 6 months my FNB account was not debited, however payments were being debited from an invalid account number (which is the correct account number) and therefore i've been paying penalty fees. I tried contacting Nedbank on a daily basis via chat services (Which is the worst ever) and always requesting for someone to rather call me as the chat gets disconnected very quickly and i then have to explain my situation again and again. Eventually i spoke to a lovely lady Lorna who deleted my FNB account and added a Capitec account to be debited. Today i am trying to get hold of the collections team as my Capitec account was not debited. A lady called me as i first had to advise her that maybe i should kill myself for this situation to disappear and she transferred me to the Collections department. I am still waiting to be helped. The call is currently on 20 mins and there's no background noise or an operator speaking. Nedbank is the worst bank to deal with as they have all these features but no help at all.
