The Link at /complaints is broken.

1. The routes are already implemented in app.py
2. Just fix the bug and make it work.

Hi, I noticed the issue with the /complaints link (#14). Since the routes are already implemented in app.py, I’d like to work on debugging and fixing the bug so the page displays correctly. Could you please assign this issue to me 🙌
