Cards not working, No one seems to be able to help

Have been a customer with many personal and accounts for my businesses. Over this time I've he'd a pretty good banking experience, however, the last 8 days have been extremely frustrating, and I'm at my wits end as this really is affecting my business as I am unable to do daily transactions.

My cards are not working, for two different account, I had disabled as a security measure. I then re-enabled them however they don't work anymore. I have spent so mny many hours speaking to FNB on secure chat to try and fix this, however they keep telling me everything is fine and the cards work, they don't!

Under my accounts on the FNB app it says no cards are linked to my profile at all, however, to them it appears fine. I am unable to transact at all on these cards or perform any daily business activities which are vital toy business, please help.
