I had similar experience also. Taxi drivers runs as they wish. Sometimes they are not interested to make trip to the location we need to. They just move on without picking us. Couple of times i had fought with them for not using meter. At last they agreed to use it when i told them that i will inform their company. It really makes bad image to the country. I have been working in UAE for the past 7 years and was using Taxis and never experienced such problems. Concerned authorities has to take action to stop this.
