Invitation offered as a gift for a dinner in "boat fly", I make my reservation on the website and I do not receive any email. I am not more worried than that because there is an address on the invitation card. Arrival on "D-day" 5mn before boarding but .... no boat. I find it strange and after research I realize that the confirmation email has arrived in .... my SPAMS. My antivirus is what I bought it for, namely protected my PC, so far nothing abnormal. Call from the concierge who told me that the boat will make no commercial gesture what I easily understand since I am for the moment only a customer "Ideal Gourmet". What bothers me is that Ideal Gourmet has all the elements to make sure everything goes smoothly after booking (an SMS reminder that costs only a few cents?) But does nothing but say : We are sorry :(( !
