This is a trap! They don't notify you at the booking stage about the impossibility of cancellation. Nowhere do they write that the amount is non-refundable. They say that I checked the box, therefore I agreed to their terms, which were described on 100 pages. On the day of the trip, I fell ill with a high fever, about which I wrote to them and asked for a refund. They refused and said that there would be no refunds. The customer service is terrible, they are not accommodating EVEN under the pretext of illness and the inability to travel in a taxi with a high fever and cough.
