👑I don't want my customers to pick a timeslot as i'm selling a full day service, how do i do that?

This is a premium feature of the app and you'll need to be Premium on the app to be able to use full day booking.

You'll need to create a "full day service" if you don't want your customers to have to pick a timeslot (opposed to what can be done on "regular booking").

Click on "my services" then click on "new service" and pick "full day".

From there you can configure the service.
