Greed versus true customer experience

I went all the way through the booking and then at the end it says payment failed or cancelled on my card So I started again and went all the way through (as fast as I could) and it said 'out of inventory' Then I started again but now the price had shot up and it worked on the same card When I inquired I was told my card had been declined, but then why was the higher price miraculously accepted. Then I was told I had taken too long, but then don't let me take the process all the way to the end and then give that out-of-inventory mumbo jumbo. What I suspect actually happened is that someone else booked the cheaper seat in parallel with me and they greedily chose to cancel my option and inconvenience me rather than lose a few rand. I knew when I sent a query that I would get boilerplate 'spin' answers which put the blame on me rather than the truth, or someone properly checking out what actually happened
