FNB worst service EVER!!!

I have been a customer with FNB for over 20 16 years. I am travelling abroad and all my transactions are being blocked and cards cancelled, even after me alerting them of my dates of travel and that if need access to funds abroad. I’ve been put in such a compromising situation. I have contacted them and nobody seems to know what they are doing. Im being transferred back and forth. Every agent giving me a different story. It’s pathetic. If you have an account with them I suggest you take your money and RUN!!! Don’t be a fool and get yourself stranded in a very uncomfortable situation.
