Extremely poor service from FNB

I started the very simple process of allowing my husband full authorization on my credit card and an additional card on the 9th of September 2022. I still don’t have this done, we are now at the end of September, they’ve sent me three different forms with no progress after that. This has been the worst experience I’ve ever had with FNB. This is simple, many families opperate this way, why is the staff not aware of proper process!!
