Do not book. Run as far as you can. They failed to provide us with two cabs - we'd booked a journey for 10 people, and instead they sent 1x 6-seater and did the journey twice over both ways. They've been really difficult to get a refund out of for this failed service, so I'd advise not booking with them and instead shopping around for local taxi providers. I've personally passed on my story to a consumer affairs journalist alongside links to other complaints and would advise others to do the same - they have a long history of pretty much scamming people and so do seek help if they owe you a refund.
