Reserved a taxi 2 hours in advance but it did not show up on time. Called Richmond taxi at 5 minutes overdue asking when the taxi Will come. The operator told me that at that time no taxi is available to be dispatched. He only said to me that when a taxi is available it will be sent to pick me up. I asked for an ETA but was told that I could only wait. Then why took my reservation? Why should I call ahead to reserve? Eventually I waited for 20 minutes before my taxi arrived.
