I paid in full based on a friend's recommendation that they were good for an airport transfer in Paris (you have the option of paying 25% to confirm the booking and balance to be paid in cash to the driver). I was stupid to trust the system as I was trying to minimise carrying cash in Paris. Connecto will ask for your flight landing time during booking (not your preferred pick-up time). Due to slowness at arrival I was out 5-10 minutes beyond their 1 hour wait time from 'landing time'. There was no driver, no replacement car and definitely no refund at least for the 75% that I should have paid in cash if I had chosen not to paid in full in advance. So both driver and Connecto gained full amount and I was left with a sour start to my holiday and after traveling for over 20 hours. If you really want to use them, then DO NOT pay in full. Anytime happens and they will not honour you as a potential future customer. If possible just don't use them.
