Applied at Aldi for Unknown

I recently applied for a position at Aldi and was invited to a one-to-one assessment last week. However, I encountered a frustrating issue with their recruitment process. There were no available booking slots for the assessment, and I learned that my application would be automatically withdrawn if I didn't secure a slot. As of today, it shows that I have no events scheduled, which leads me to believe my application has indeed been withdrawn. I've reached out to the Aldi recruitment help team via email, but it's been quite some time without any response. I'm wondering if anyone knows how often booking slots open up, as I'm feeling quite stuck in this situation.
