Hi @teamsupport, thanks for your message.
I completely understand your feelings and regret for this kind of misunderstanding has happened. From our side, we always try to ensure all our users are provided with a clear product description and are free to ask as many questions as they need before the purchase.
In this course, there are seven lessons witch are made for instruction purposes and are showing how to work with an external API call from Google.
Basically, this course covers up mostly the workflow process and is less focused on design, which can be different for each use case.
The Google and Stripe services are constantly changing their design to look more user-friendly and it differs from our course, but the main functionality stays the same.
Every error that you are getting from Google services comes with a short description, for instance, error 400 means redirect URI mismatch, which means when you preview your bubble app and try to connect to a google account, that URI is not included inside your dashboard.
Also please check once again your API Connector settings inside your Bubble app, sometimes a missing letter or a checkbox might cause issues. So it’s better to follow our video one more time on how to set it right.
Please make sure you have an existing event in the Google Calendar of the user you are login in.
I will attach below screenshots and a video with setup for the app that we have built following the Smart Calendar Booking System Course, please compare it with your app.

I will try to do my best to solve any problems you encounter, please try my suggestions and let me know if they helped.
Also regarding your request for a refund, to my sincere regret, we do not provide a refund for the course according to our Terms and Conditions.
Looking forward to your reply.
Best regards and Happy holidays ahead!
