I got an invitation from my friend to sign up which said I would get 50% off on my first 3 rides. Once I signed up using the invitation link I got promo code applied automatically which was only 20% off for the first 3 rides. Then I tried entering promo code from the invitation link I received and since I had already booked a ride it said this code is valid for the first ride only! What is all this mess?? Can't trust an app like this at all!
