Charge.
I was charged more than the trip cost. The total cost on the drivers meter was £5.70 and about 6 pounds on the app but I was charged £7.50 from my bank
Waste of Time
Downloaded the app and tried to register but wouldn’t let me complete registration because it needed to send a code to my mobile but then wouldn’t accept my phone number even though I’d entered it perfectly. Kept saying “error - app not verified” and that was that. Rubbish.
