Discovery Bank incompetence

In January 2022 I provided the Bank with my wife's FICA documentation and received a response confirming that the required information had been received. My wife and I are 80+ years of age and my wife is the secondary card holder on my card a/c. They actually asked for her work details as part of a proof of income! Every month including July, I receive an email asking for FICA documentation and adding that failure to produce this could result in the card being blocked! What a sick joke, although I don't see the humour... I pay an extra R35 a month for this card which is hardly ever used as I am present when making a purchase. Maybe it's easier to cancel the card, but will Discovery keep charging me R35 monthly? And will I still receive monthly emails?!!! Adrian Gore does not seem to have the people in place that share in his vision!
