Have been trying to book a flight on the BA shareholders website and found some good prices. Everytime I tried to book it told me the flight had sold out. After three calls to BA and ten attempts to book I am told that the ticket had sold out and should not have been offered. They will not honour the price. Is there any recourse? They made an offer I accepted and the did not honour the offer. As its BA no surprises but who do I complain to?
