I was really excited to use this service because I could book the cab online. I needed to make it in time for restaurant reservations at 630 PM, so at 4 PM I used the option to book for a future time. I asked for the cab to come at 6. Someone called to confirm this with us.
Now by about 607, the cab hadn't shown up, nobody had called, and I hadn't gotten an email. I called the dispatcher, who told me he was really sorry but that he had been trying to get a cab since 545 and nobody was available. So basically 10 minutes after the cab was supposed to come, I was told that it couldn't, but the only reason I found out was that I called. I would never use this service again, because online booking is only convenient if it actually works.
Cons: Unreliable, no communication
