Hi - if you go onto the Orihuela council website and go to contact Orihuela Costa, they do not give an email address just:
Ayuntamiento de Orihuela Costa
Plaza del Oriol, 1. Urb. Playa Flamenca
Ctra. N-332
03189 Orihuela
Tlfn: 96 676 00 00
Fax: 96 676 12 50
You could try emailing Stefan Pokroppa who is the person responsible for issues to do with the expat community and his email is stefan@orihuela-costa.eu
However, as Sanchez says, they will probably totally ignore you whatever way you communicate with them. I'm still waiting for a response from Stefan after meeting with him personally twice last year! Communication is not their strong suit!
Good luck.
