How can we NOT help

So one of family members had to travel oversees for an emergency. He phoned FNB the afternoon before or morning of his flight to find out whether er he will be able to use his credit card oversees. He was informed that all is in order. Needless to say when he wanted to withdraw cash he was unsuccessful. I phoned fnb a couple of times to find out what should be done. One guy eventually put me through to cc authorization where I was informed that the account holder must phone himself. He tried to phone Thursday but heard for an hour that they are experiencing a high call volume. I emailed fnb customer care on Thursday night explaining the situation and requesting that they contact me so that we can get my family member's account accessible. Heard nothing. So last night I tried sending money with my fnb app. Guess what they are experiencing technical errors!!! How convenient. They always advertise that their banking is so easy. Well, I think not. I have experienced nothing but frustration during these last few days. How is that helping their clients? Maybe fnb should first help themselves.
