Desperately need advice. Nearly 2 years ago I purchased a voucher for my daughter and her fiance for a hot-air balloon flight with Adventure Balloons UK. After a year, and a number of flight cancellations, my daughter reluctantly paid £80 for a one-year extension of the period in which a flight could be taken. A few weeks ago she, and her now husband, went to take a booked flight, but was told she could not fly due to her being in the early stages of pregnancy - which they accepted. However, the company has now written to her to tell her that the vouchers are now void, and no refund will be made. I have since checked Adventure Balloons UK on a number of consumer sites - notably Trust Pilot (no pun intended!) - which has revealed that this company has a ghastly customer service reputation with a large number of similar incidents. My daughter has politely written to the management to ask for a refund given the circumstances, but has received two very blunt refusals. What action could/should we take?
