I surched a flight Stockholm-Zaporizjzja with Skyscanner the 17/6 2019. The cheapest alternative was Bravofly. I booked the flight and they forced me to take insurance. I didn't notice that Bravofly had changed the date to 1/8 2019. I suppose if I had noticed and changed it, they would have raised the price and they wouldn't longer be the cheapest for the actual date. I tried to reach Bravofly by phone to change or cancel the flight. An automatic voice directed me to internet. Internet directed me back to the phone. At last I got a automatic popup on Internet that said that refunding for my flight wasn't possible. Why did they then force upon me a insurance for cancellation. And further in the popup "You don't need to inform us if you refrain your flight...". What does that mean? Are they free to sell the flight again without my confirmation and without paying back.
