FNB JUST BLOCKS ACCOUNT WITH NO NOTIFICATION

On Saturday I had to leave my groceries at the till as my card was not working, I called and was informed that it had been suspended due to non payment, which is already strange to me as my debit order date is the 31st.(ONCE AGAIN I WAS NEVER INFORMED) I was on hold on Saturday for 25 minutes where after THE AUTOMATED response said it is outside working hours... Okay, today on Monday 28/03/22, I've not been assisted via secure chat, I have been on hold for 90 minutes and I still don't have any access to my account. THIS IS BORDERLINE SADISM TO JUST BLOCK SOMEONES LIVELIHOOD AND NOT INFORM THEM OR GIVE THEM A WAY TO AMEND IT. Really disappointed in FNB.
