Our transfer crashed. Next steps?

Last night we had a transfer booked for 6 people from our Airbnb in Alcudia Mallorca to Palma airport. As soon as we all sat down the driver moved forward and hit the car port on the roof, we were all shouting stop and she carried on driving and smashed the sunroof window, causing the glass to shatter all over us.

The driver spoke no English so I was politely communicating through Google translate, asking if they are sending out another taxi, to which the driver angrily said you either get in this taxi or you don’t get your money back. (As she was sweeping shattered glass all onto the driveway.) We did not feel safe in the vehicle and so we spent €77 euros on another taxi to the airport as we had a flight to catch.

This transfer was booked through Ryanair and I’ve now twice tried to make a claim, the first time it came back within an hour saying resolved when nothing had happened and the second time they closed it instantly. I’ve tried to ring up the Ryanair phone number and the robot just says all claims must be done on the website and hangs up.

Please advise me on our next steps. I’m worried that the Airbnb owner will keep our deposit due to the damage, we spent £220 on the transfers which we only used one way and then spent a further €77 on the taxi to the airport.
