Shameless thieves and incompetent service.
Our flight from Paris to Prague planned to take off at the end of March 2020 was canceled due to covid. After a lot of patience, and trying to understand the difficult situation the airlines are in, the only thing I got in return was a bad attitude from Czehch Airline's customer service, 0 communication on the matter and 0 refund.
Up until today, I am trying fruitlessly to request the money I paid for the service that never took place. Of course I understand, that they will never pay me back.
