I booked a ride to the airport for 51,48 Euro. Hoppa replied with an email right away asking me to cancel that booking and book again with additional information. I filled the instruction and had to pay again 51,48 euro. The day came but no driver appeared to pick me up. I had to call a Taxi. The taxi charged 39 Euro, a lot less the Hoppa. I contacted Hoppa for a refund. They refused to refund the first booking because I canceled it. Even so Hoppa instructed me in their email to cancel. For the second booking they implied that I m lying and claimed the the driver provided the service. I paid 103 euro and got no service. Bad experience!
