This is a very strange booking platform riddled with problems. Firstly, I booked a taxi to take me from my home to London City Airport. As the price was so good, I thought I'd double check with the taxi company I had been assigned to that they were actually going to turn up. They told me they had nothing to do with Jumpyn and cancelled my trip. To their credit, a Jumpyn advisor contacted me straight away and told me that they had spoken to the company and they would indeed take my trip. The taxi company called me to confirm this too but also added that the price was a 'mistake' but they would honour it anyway. I decided to try again and book a return taxi for a couple of weeks later, going back from London City Airport home. One fare was coming up as just over £1 on the system! I knew this must be a mistake so I went for the 2nd best fare with the taxi company I'd previously been assigned to. Again, this trip was cancelled because a £15 airport surcharge hadn't been added automatically to the fare. This may have had something to do with the fact that London City Airport doesn't properly show up on the site's searches. You have to say you want to be dropped off somewhere in the vicinity - eg. LCY DLR or the Air France building. All in all, great prices but pretty misleading with a shambolic booking system. If these guys want to grow, they have to take a long hard look at their systems and quote fair prices so customers aren't wasting their time with misleading prices. I would have rated one star, but the quick response to the issues with my first trip have been acknowledged in my rating.
