Use this code "w4fdf" for £20 credit with Uber.. The app for taxis.. Install it on your phone and put in the code when registering. they're always on the road and take about 10 minutes to show up to anywhere you say on the map!! It's like they're trying to take over london and must be loosing money with this new formula to try n get everyone to use them.. Honestly install the app and put in the code "w4fdf" when you initially register.
