Lost Wedding Photos Advice

Hey all!
My wedding photographer sent me all of my wedding photos and I was swooning over them for days. As I was purging which ones I was going to get printed into a wedding album I realized most of my family portraits were missing. My out of town family, extended family, and nieces/nephews. These are the only photos I have with almost all of my non-immediate family. I emailed her to ask her to send them and got hit with the devastating news that she could not find them. She said she believed they were corrupted on the SD card. She said she would try to do everything she could to recover them. I googled the issue and I am hopeful that these photos will be recovered. I am growing a little wary though because this happened two days ago and I haven't received a definitive yes, I can recover them or no, you are out of luck. She has been actively posting other photos on her social media accounts so I know she has the time - she just hasn't been dedicating it to recovering my wedding photos. I am wondering if she is truly going to try or if she is going to put me off and then stop responding. I am going to be patient and see what comes - my anxiety is taking over a little b/c if it was me, I would be immediately making every effort to recover my client's missing photos knowing they were important to them. So my question is, do you think I am entitled to any refund if she can't recover them? She sent me over 700 photos which had the ceremony, the reception, portraits of the wedding party, etc. But a huge, important set of pictures is missing and I don't have these memories with my family members. My heart physically aches that I might not have these photos.
