VFS South Africa website bug / impossible to print application form

The South African VFS website has terrible user experience / does not work properly. A few examples: 1. If you click the "Back" button on your browser, it logs you out automatically. You then cannot log back in for 20 minutes (it gives you a "duplicate error"). 2. Any time I click the "Download appointment letter and checklist" button, it logs me out and then I cannot log back in for 20 minutes. This means it is LITERALLY IMPOSSIBLE to print the application form necessary for in-person submission. 3. When I click on the application number (left-most cell in the table), it takes me to the actual live application again, which allows me to go through and submit again. This should not be possible once it's been submitted. Also, when on this page, I cannot navigate to "Print" (it shows as a tab but you can't click it). Therefore to try to navigate back to the page to print the materials, I clicked the "Back" button and ran into problem #1 again. I found these bugs on Chrome, Firefox, and Internet Explorer, across both Mac and PC. (I really did try everything.) All these bugs were made worse by this 20-minute timeout rule.
