FNB IS FAILING ME.

Yesterday, I was at the shops and I tried to swipe my card and it declined and then I tried to withdraw it declined, I had an emergency and I needed to buy airtime using the app and declined saying "your request cannot be processed" I'm so irritated, my account is still new, I haven't had it for less than a month, I thought I was leaving the other bank for the convenience of FNB but clearly I'm being proved wrong here.
