Having Difficulty Scheduling a Schengen Visa Consultation with VFS Global

I've been trying to book an appointment for an Austria Schengen visa through VFS Global, but I just can't seem to get one. I've tried from different cities, but I keep getting the same error message. Here's a screenshot of the error I've been getting. Although there seem to be open slots for July appointments, I'm having trouble choosing a specific date and time. Can you please help me? We have plans for a holiday in August, and we're running out of time.
