Best of luck Ketsy.
You know they have it. If they aren't responding, they may simply be trying to regain the upper hand.
If you phone them now, will you be letting them have it?
As it's been a few days, can you perhaps write another email?
Shorter this time. Tell them this is what you are going to do. As them for their opinions.
That way, you still have your cards, so to speak, but you leave them an opening to come back.
