SHAME ON YOU DISCOVERY BANK

Once again, problems with Discovery Bank. This morning 25th November I tried to use my card to purchase for an item. My card and my entire bank account has been blocked due to an outstanding proof of address. I have called Discovery Bank about 5 times today and I have sent my outstanding proof of address via my app. I have been told to wait 2 days for this to be rectified. Discovery Bank how do I purchase food or pay for petrol. They always say they will come back to you but of course, no one ever does. I am so, so tired and seriously thinking maybe Discovery Bank is not the best bank to bank with! There is absolutely zero communication.
