I booked via Taxicode a journey yesterday from the airport back to London due to the railstrike. I receive a call a few hours before the scheduled trip and was informed that they have to upgrade the car due to the luggage, which was entered in the booking process and on which basis the booking took place. On top of the £100, they wanted to have additional £30. When I wanted to cancel, the caller declared that there wouldn't be a refund. I decided to go along with this blackmail due to the circumstances. The pick-up, the journey was fine, but due to the scam practise I can only recommend to avoid Taxicode.
