Discovery Bank is not so easily discoverable..

I am so frustrated. I used to receive, like any other banking system in the country, my Discovery Credit Card statements by email. No worry, no fuss. Then Discovery Bank was born, and now I am told I have to download the app. When I did so, I was told I must now enter all my details, including my personal income. Seeing as I have had a credit card with Discovery for several years, I do not see the point of filling in all this information. Why can I not just get what I require? Then I emailed Discovery, asking for assistance. But now their mailbox is full. How's that for professional??? I guess I'm going to have to phone them and sit in a waiting queue for ages until they eventually answer my call. How backward is that????
