Dear Mrs Deborah,
The option that you booked was "Accademia Entrance tickets". The price that you paid is related to the option of the single ticket, no guided tour is included as stated in your voucher. The description you read is about the whole activity, then when you make the booking you can select the option you prefer: guided tour (in the language you like) and entrance ticket. If you select the entrance tickets, no guided tour will be provided, you only have your tickets to enter the Accademia Gallery, nothing else, therefore the price that you paid is much lower than the one for the all package: ticket and guided tour.
Please withdraw your negative review as we are sorry that our activity did not meet your expectations but you had what you booked for.
Best regards,
ACCORD Team
