Cannes, Antibes, and Saint Paul de Vence Tour from Nice

Anthony nice and friendly guide, but a bit rush to go to three cities - Cannes, St Paul de vence and antibe.

I checked the reservation confirmation email at the time of reservation. I didn't have to check the email and it was my fault for not checking it because the emails piled up. When I inquired, they said that they had sent an email in advance, so I checked and there was an email saying that the number of people was full in 3 days so I should change the schedule and that it would be automatically cancelled if there was no reply. The automatic cancellation was not set and I didn't realize it until the day of the trip. It's absurd that they sent an email 3 days after receiving the reservation confirmation to change it to that status. Klook kept showing it as a reservation confirmation so I was suspicious and didn't have to check the email. On the same day, I got a reply saying that Klook and the company would discuss it and respond within 48 hours. They said that they notified me by email 3 days later so they decided it was my fault for not checking the email that arrived. I admit it. I wasted another day.
