Hi Grandma ~ Welcome to the Forum

!
As Grace has so kindly and quickly provided you, that's the place to effect contact. Seeing the Fax number provided, as well, with your deadlines looming, my suggestion would be to email, write, and fax your request, noting of course in each one that due to your previous attempts, you're trying to cover your bases, as you don't want to miss out on the chance to include Leonard

. Your Subject line might include "Permission Request w/Deadline Looming" ~ hopefully, amongst the thousands of emails they must get each day for various reasons, it might catch someone's eye and prompt a response. Of course, I'm sure you'll include the line, as well, in your initial email.
As to my suggestions, you may have, in essence, already planned everything I've suggested. Even so, might as well reenforce it... and you never know

. No guarantees on the effectiveness of my suggestions; just thinking of what I'd do in similar circumstances... with the looming deadline making all the difference in the outcome... and with previous attempts having failed.
The very best of luck to you in your mission. What a shame it would be to have to leave it out.
Interesting how Leonard meets our needs at all life levels. Really liked your description of how it's been with you. Especially as we're growing older, it seems to me we find additional levels of comfort in his words.
