Saying you do not have a detail no longer replaces vehicle information you already supplied. The receptionist keeps a request for registration aligned with the detail currently being checked.
If registration is unavailable, other details can be collected first. A required registration still needs to be supplied before the booking is confirmed.
Keep supplied vehicle details
Uncertainty such as saying you do not have a detail preserves vehicle information already supplied, rather than treating that phrase as a new make and model. Explicit corrections can still change those details.
Keep the next answer with the right question
A registration question cannot jump ahead while the vehicle make and model still need checking. When registration is unavailable, the receptionist can collect the other details first; any required registration remains necessary before confirmation.
This update addresses those intake failures. Availability suggestions and response delays remain under review.
