Long story short, my friends and I flew with Vueling and they lost our luggage. They’ve done nothing so far except ignoring the problem. They’ve failed to give us any kind of status on the luggage or offer any kind of compensation. Some of us even had our work laptops in our bags. It’s been five days with no response. Several times when we’ve contacted them, they’ve hung up the phone on us. It’s been a terrible experience, and since we can’t get them to do anything reasonable through their normal customer support channels, I’d like to escalate it by filing a formal complaint with some sort of government or legal entity that helps hold businesses accountable. The only problem is that I don’t know who to report it to in Barcelona/Spain. I speak good enough Spanish to file a claim, but since I don’t know what that sort of entity is called in Spanish, I’ve been having trouble finding where to do so.
TL;DR Where can I file consumer complaints against a company with the government or a legal entity in Barcelona or Spain?
