FNB - Minus 100 for Non-existent Client Service

Upon using our card to purchase something the card was declined although the funds were in the account to cover the purchase. Subsequently the card was blocked for a reason unbeknown to us to this day and we were unaware that FNB had, in their wisdom, blocked the card. No verification sent to check if it was us using the card. No courtesy call to inform us the card was blocked. Not even the decency to send a SMS saying they had blocked the card. Absolutely nothing. Yesterday my husband had a business lunch with his attorney. What happens?? When the lunch ended and he had to pay - guess what - the card is blocked - we were totally unaware that it was blocked - and he cannot pay. First National Bank - how do you think this made him feel?? How embarrassing when he cannot pay because the bank has blocked the card for a reason only they know!!! This is totally unacceptable!! At least have the decency to inform the client that the card is blocked due to x,y,z. And their famous saying "how can we help you"!!!!!!!!! What *******!!! Phone the client, say the card is blocked and this is how to unblock it. Don't just leave it for them to find out at the most inopportune moment!!! I went online to see what had happened and only then did I see it was blocked. I unblocked it online and still it did not work. Nedbank on the other hand has the decency to phone and ask if it is you using the card if they suspect something is not right. That is service - not the service we received from FNB. Is FNB going to write a letter of apology to our attorney for this debacle??? Apologise to my husband for this mess??? Probably not as they don't care!!!! This is not client service at all!!!!
