((((Beau)))) awwww, seriously. No response at all? That is awful
generally, at each company or firm, there is a procedure in place to schedule meetings. An Outlook meeting invite (date, time, location), with a few words describing the purpose of the meeting in the subject line, and then a short note / mini outline of the agenda in the body of the invite. The day prior to the meeting, you can send a lil reminder via email.
(*it is helpful to schedule the meeting around "breakfast" time, so you have an opportunity to provide a small continental breakfast....do you have petty cash that you can draw from? Or can you expense the meeting?)
If you dont receive a response after the second attempt, follow up with a call to their assistants or if they dont have one, leave a message stating how you are looking forward to seeing them at the meeting...and to please bring their appetite, as breakfast will be available.
A little nosh goes a long way
If they continue to dismiss your requests, you have a paper trail to reference when you speak with hr to voice your concerns. All the best, dear

please let us know how it goes.
