Horrible service and frustrating experience

I have never been so frustrated dealing with a bank, I have phoned to get the settlement amount to close my FNB credit card. I have received 2 different settlement amounts today. I phoned again to confirm the correct settlement amount after being transferred 20 times with no luck and the last person I spoke to dropped the call. I have been on the phone for more than 30 minutes and no help received . Luckily I am moving all my accounts to Nedbank and their service is excellent.
