Very poorly
Did not provide a refund for the flight that was modified, only a voucher that I will not be able to use. When the flight was modified, they even did not provide a modified invoice. The only responce I got, was an automatic virtual assistant. Nobody bothers. Definitely I am not going to book with them again. There are other providers which are reliable, do not have this plenty of masked fees and have better price and quality ratio.
