Corona Virus

So we went with Naimoli Estates but now this Corona virus is out and because of it we can’t have the ceremony because one, we don’t know when the mess is gonna clear up, and two, we are military and it’s hard getting our family and friends on the same page. Get this though, my mother signed a contract for the rental of the place, the lodge and barn. We paid for it on full. Then myself and my fiancé went and planned out vendors for a cake and DJ and all that stuff. Added up pretty quick. Now that we want to cancel, she is saying we can’t get any of the money back even though the wedding was supposed to be in July and I haven’t eaten a piece of cake or danced to a DJ spinning tunes. We never signed a contract for each individual vendor that SHE recommended and now she doesn’t want to give us any of our money back. I understand if she wanted to keep the money for the venue but what does that have to do with decorations and other things that haven’t been set up or cake that hasn’t been eaten, pictures that haven’t been taken. Does anyone know what I should do. Again, my mother signed a contact for the venue, myself and my husband never signed anything.
