Unhappy client ready to move banks

I have been banking with FNB for over 20 years now. We have requested an extension on our home loan to build on and FNB denied us after many fights, we then moved our home loan for Nedbank and got the extension to expand our house. Nedbank now has a client with a home worth more. How amazing is Nedbank.

I still have my normal bank account with FNB and think I should cancel that too and no longer be a client of FNB. My card expires at the end of the month and FNB can NOT assist me in linking a new card. One would think with FNB being "the best in online banking" one would be able to do this with no hassle. Well, that is not the case. I have spent hours on the phone speaking to many *********** people and struggling with cellphone banking denying the steps the call centre said to follow. The other frustration I have is that when you get to speak to someone at the call centre you get cut off the call completely when you go through the authentication process.

Is there anyone at FNB who are competent enough to assist me in getting a card linked in a few minutes or should I make life easier for myself and move banks? Maybe also consider changing your slogan to "How we can't help you". Then customers will not expect anything from you.
