No more access to Postcard Cabin account, still had 4 free night vouchers!!

I cannot believe this mess-- I know there have started to be changes to Postcard Cabins since they were bought by Marriott, but now you can't even log in to your account and I have absolutely NO IDEA where my 4 free night vouchers are now!! I had 3 left from a package and 1 from the buy 7, get 1 free that they used to do. I've emailed Marriott and better get a quick response because I will be so pissed if they put limits on how to use what I already bought. No email, no update on timeline, no information on the website about how to access previous nights.

This just sucks, I've been using these cabins for years and I'm done with them after this change. I'll update once I hear back as I'm sure there will be others trying to use their credits.
