Croatia Airlines

On the 3rd March I flew from France to Zagreb and then onto Split. What should have taken a 2.5 hour flight turned out to be 14 hours and they lost my luggage. After nearly three months they offered to reimburse me 620 Euros when my claim submitted came to around 2000 Euros. I was also informed that they would pay me 250 Euros for compensation in regard to delayed flights. Nearly two months later for my compensation claim, still nothing. Regarding my luggage claim, on the 5th May, I objected to the amount after being told I must claim from my insurance. My emails aren't rep**** to and nothing heard from the airline. We have used them for over eight years and if this is the way they treat their customers I shall not be using th e m again. They are the worst airline, they ignore correspondence and do not take responsibility when they are at fault for losing my luggage.
