We booked transfer from Cologne to Frankfurt Airport via website at 268 Euro on Oct 18, 2022. We want the driver to pick up on Oct 22, 2022. At 11.30 AM. After that we didn’t get any confirmation until another day. We have to Email to ask them. Oct 20, 2022 in the evening, we got the message that they can not find the driver with the same price(268 Euro), they said they find another driver at 336 Euro. We have no choice because it’s the last day. So, we confirmed them. After that, at 11.30 PM, they told me the driver is not available. They canceled us in the last minutes at around 11 PM before pick up time 11 hours.
