My wife and I arrived at Santorini airport September 3rd with our 8 month old infant. To our surprise the Viator transport we booked had already left. After some investigation we figured out that there was another James Ryan who arrived at a similar time and had booked transport with another company but ended up taking our Viator spot by mistake. Viator's staff member at the airport George was dismissive, disrespectful and incredibly unprofessional. He refused to admit that an error occured even though my name had been scratched out on the Viator arrival placard and the other transport company approached me separately to say their James Ryan had gone on the Viator transport. George eventually offered a small car to transport us with no baby seat, not suitable for our 8 month old infant. In the absence of a baby seat I asked George to help us get transport in a large van (like the van in the picture on our booking) but he said no. I asked him to call his manager to explain the situation as our phones were not working and he also refused. He also began to say he could not understand me having spoken fluent English at the start of our interaction. We were forced to organise private transport from the airport with a different company who were very empathetic and very helpful. They (Choose Yafy) made calls to find safe transport whilst we sat outside for 60 minutes in the heat with our 8 month old. During this time, George remained in the terminal talking to his colleagues/friends. I have to say I have never come across such an unhelpful and unprofessional representitive before. I spent the last month trying to contact Viator who have just now finally issued a refund and made no apology for our experince or the difficulty getting a refund. This is hands down the worst consumer experience we have had. We will never use Viator again.
