Hi
We remember this booking was originally booked for 1:00 PM and then we re booked for 3:00 PM and there was nothing extra charged by us, if you still have the tour voucher you can located the Agent Name on it. We give out vouchers to 100 of Guests on daily basis and never charged extra once the booking is done unless the guests asking for an upgrade.
Please do feel free to share your booking Reference Number so we can check on the same for you in detail and get back.
We appreciate your time and review this really helps us to provide better service and correct our errors.
Thank You
