Spanish ombudsman
The Valenciano ombudsman is the Sindic de Greuges. Send copies of all your official complaints, photos, etc. When they receive enough complaints about the same ayuntamiento, they investigate. Ondara has a reputation for being particularly catatonic when it comes to enforcing its own by-laws, sadly.
