YOU HAVE A NOTIFICATION
App is fine for booking a taxi, type addresses, time for pick up etc. car comes somewhere around the time you’ve booked for and tends to drop you in the place you requested. I always seem to have the big red notification dot showing a notification but cannot for the life of me find in the app where it’s coming from. Either keep notifications off so you don’t know when your taxi is coming, or delete and reinstall app on a regular basis.
