Booked flights, and they called to say they weren t booked and that the prices had gone up. Went ahead and booked but since covid was told the cancelled flight would be refunded between 8-10 weeks. It has now been 4 months and they keep telling me they are refunding it but there are delays, which is now an obvious lie. They are still trying to charge me administration fees despite their but administration and even worse service.
