FICA saga!

My husband and I have been FNB clients for close to 20 years. Recently I received an sms saying that I needed to provide my tax details. I called the number on the sms and was told to complete forms, which I did and sent to them. On the 17th of November they posted a note on the App that my account saying that I would not be able to transact on the account on the 21st of November if I did not confirm my FICA info and they provided a number to call. That morning I could not use my card to pay for petrol. I called confirmed details. I lodged a complaint after the call. Today I could not pay for groceries. Went back on the app. I was told to upload docs on the FNB site. When I go onto the site it says no outstanding documents? Now I must send docs to an email address.
