I cannot change your experience but i am very sorry you felt the way you did and it may seem like a default response but this is not according to our internal policies and regulations.
I am honestly shocked at your experience and would like to examine internally what happened. Could you provide a bit more information about the person helping you that day? Anything would help. Maybe you remember the day you were here and some characteristics about the guide so we can pinpoint who it was and discuss it with her.
Nevertheless we will forward your comment internally as well as a reference for future visits.
Thank you for taking the time to reply and i hope you can provide some more information. You can contact us by emailing at firstname.lastname@example.org with any more info you have and we would appreciate it immensely if you could help us more.
