Booked British Airways flights through Travel Up, but unfortunately flights were cancelled. BA confirmed full refund sent to Travel Up, however, Travel Up will not give full refund. After weeks no contact, received one email saying the will take an admin fee. They updated their T&C's in February 2020 to enable them to take an admin fee (I booked December 2019), and therefore not legally contracted to new T&C's.Therefore, they are illegally trying to give me a reduced refund and I am receiving no contact to discuss this. Awful customer service, not professional and worst of all abusing their customers rights. Worst company I have ever dealt with unfortunately - here's to hoping I ever get any of my refund back...
