My walker did not arrive with the rest of my luggage. The handling crew (via partners) that works for British Airways is completely unhelpful and don't even answer the phone. I went to the airport 48 hours after my arrival to try to retrieve it but no one was in the lost and found office. After looking for someone to help for an hour, someone brought me back to look through some lost and found luggage but didn't have access to all the rooms and I didn't find it. I spent the next 3 days calling and being redirected to numbers that no one answers and people who barely offer help. I'm told they will follow up and now my holiday is half over and I haven't been able to leave my daughter's flat because I can't walk without my walker. British Airways is supposedly following up with their "valencia team" and will get back to me in 24-48 hours although they said that on Saturday too... the lack of accountability is beyond frustrating.
