Eurowings Flight delayed/cancelled

After some advice please (apologises if in the wrong area)

A mate was/is at Alicante airport this morning (3/6/19) for a flight to Dussledorf then to Manchester

The flight was scheduled for 09:45 departure, it was delayed several times until 14:20 before being cancelled at about 15:40

Now is where the advice/help is required
Despite efforts to contact Eurowings via phone or Skype with little success
And with no actual airline desk just servisair to assist for onward flight assistance back to the UK

My mate has booked his own Easyjet direct flight back to liverpool tonight at 23.35

So he has been at Alicante airport since 07.00 for a 09.45 flight

Where does he stand with Eurowings compensation for his flight home


Also from what I've been told the crew boarded the flight but a shirt while later it was cancelled

There is talk of the original flight being diverted to Barcelona due to a medical emergency, so I'm guessing g the crew may have run out of hours

He also needs to be home tomorrow for work so after being left in the airport for the best over 5 hours with little or no assistance, he's sorted his own flight home

Any advice please would be appreciated

Thanks
