FNB - Zero Customer service while overseas

I have been trying to sort out my FNB bank account and banking app for over a month while overseas. After it was closed they gave me an email address to resolve the issue just to close that mailbox without any alternative email address. I have phoned and email every single email address I can find with absolute zero results. If you are going overseas just close your FNB account it will cause you less stress in the end. I'm at a point where I'm not going to pay my credit card and wait for them to contact me, maybe that's idee of customer service
