City Airport Taxis (WEBY Ltd.) is only an agent. They do not guarantee the transfer costs as agreed, even if it is prepaid. Prior to our group travel to Courmayeur in February 2024 we arranged for pickup at Genève airport for 9 persons. The agreed price was 1255 Euros for transport to Courmayeur and return a few days later. The transfer down went very well even including some flight delays. On the day of return, we were informed by City Airport Taxis that their supplier had cancelled due to problems with their vehicle and we were presented an alternative option with a new supplier. However, we had to pay an additional 572 Euros due to short notice. When we protested, we got the option to cancel the return to the airport and get a refund. We had no real option other than accept the new offer since we had a flight in Genève to catch. We complained to Bookings and all we got was an “apology for the inconvenience” from WEBY Ltd. Our recommendation is to avoid this company and seek to make agreements directly with the suppliers. In any case, be aware that the only service they offer is to connect you with drivers and arrange for payments.
