Never Again - Virtual Flights Sold

I just booked a flight to Mombasa via Lastminute. Everything went well online and the money was taken. The confirmation email was received immediately - but from BravoFly, not Lastminute (same set of people cowboys it would seem )However, after a few hours, they emailed me to say the flight was no longer available. ( It was still being sold on their website however many hours later). They offered me an alternative at £110 more. Unfortunately the alternative was similar only in that it flew on the same dates - totally different departure and arrival times as well as a different airline. I mailed back stating that the alternative was unacceptable and that I wanted my money back pronto. We have now to wait at least 72 hours for a response to any customer service queries as they are busy - possible sorting out all the foul ups like this.
I am at present over £1200 out of pocket, but fortunately paid by Visa.
It is certainly possible for availability to be checked automatically BEFORE taking money. It obviously does not suit them do so - after all if they do this enough times they get a shed load of money for doing nothing but creaming off the interest before paying back.
Bad companies, Bravofly/Lastminute.
Back to Expedia for me.
