cannot order delivery of a new bank card

After calling the call centre 2 times requesting to order a new bank card i was twice referred to order on the app. When I enquired HOW to do that since I have an active app but cannot find out technically how to do it, the call centre could not give clear instructions. i than decided to go to a bank (Boulders) and I got somebody at the bank to go in my app and order for me which was done. Now i need to set up a delivery address and time and the webiste is offline for that! Im really hating this app as the call centre wants to push everything to it whereas the app is not user friendly. please call me back to give over the phone card delivery instructions since your technology is letting you down.my contact is..
