the product you booked says "borghese Gallery admission ticket" so I don't know why you suposed there's a guide there.
Upon checking your booking, made for May 1st at 1pm, the entry ticket has been sent to you on April 7th.
The phone number on your booking confirmation is my personal number. Yesterday (even if we were closed) I took all phone calls I got but I have no missed calls. Try please to contact me again so that we can investigate on what happened
The price of the ticket you saw on site is the price of 2019....if you check on your ticket it report a different price.
For sure we don't work for free so your payment includes also our commission.
