Thank you Ethans for taking time and writing the review. I'm very sorry for the confusion of the voucher and a glitch in our system to show the earlier start time. As soon as we are aware of that, we sent out several emails to inform people who booked this tour of that. Your guide assigned to your tour is not a substitute, and I think there is a misunderstanding. There was a different guide assigned to the tour that day but he was sick so your guide was called into work. She has done pizza classes, and many pizza tours related before, and is very knowledgeable about Italian food with a culinary background and as a result, many customers liked her. For about 65 Euros per person, you got to go and eat at 4 different famous pizzerias in Rome, and make your own pizza from scratch with a pizza chef, and the guide and also the established pizza chef explained to you about history of pizzas, different flour, different types, the dos and don't when making pizzas...( a professional pizza chef working at a famous restaurant teaching the pizza class to you and he s been doing for years will for sure 100% have all your questions covered, and when we asked always several times do you have any questions, you didn't state you have any questions at all ) I am not sure if for some reasons you were not paying attention during the tour or you just wanted to find a reason to complain to get the tour for free, otherwise , you will write a bad review ( We have customers like this once in a while ). I am very sorry that you are not 100% satisfied with your tour, and we could offer you to do this tour again in the future with a different guide and completely free of charge and we hope that you wont find anything to complain then, but a full refund now since you already did the tour, took the class with a well established pizza chef on how to learn how to make pizza from class hands on, is not fair. I'm very sad to hear this, but we sold what we advertised and I am sorry if you were not paying attention during the tour, but all that you complained was explained not only once but twice first by the guide, second by the pizzaiolo. We have been doing these classes for years, and the pizza chef isn't new to this and so was the guide. Thank you again for taking your time to write the review.
