On Wednesday last week, Alicante came up with a message that all appointments for the week had been allocated but Elche had appointments. Maybe they get very busy and you just have to keep trying. I should imagine they would be rather busy at the moment with the amount of applications.
Under the advice to changing a UK licence, it states:
In person , delivering all the documentation at any Headquarters or Traffic Office .
- You must request an appointment online or by calling 060.
- When requesting your appointment, you must indicate in "Type of procedure" the option "Office procedures", once there, select the option where the procedures related to drivers are covered as the processing area.
- We will not be able to assist you if you make an appointment in any other way.
