Hi, this is the OP.
I forgot to report back a few weeks ago. I am not sure where I left the updates so apologies if I bit of this is repetitive info from previous posts.
I finally got a call from a member services cast member who couldn't give less of a you know what. They listened to my story and basically said that the $50 courtesy credit I already received settled the matter.
At this point, I took the suggestion of people in this thread and one other thread that told me to email William Diercksen & also the member services email address.
A couple of days later and after a few back & forth emails, I got a call from another cast member in member services. After introductions and the disclaimer that we were on a recorded line, the cast member basically spoke for several minutes. She told me (parphrasing) that she could not believe what I went through, her disbelief at how many many things went wrong, pointing out things she knows should have occurred based on her training, experience, and knowledge as a cast member, etc.
She heard me out, we had a discussion, there was empathy. Then she asked if I would be OK (her words) with a full refund of the points used on that stay. Getting 99 points back exceeded my expectations and of course, I accepted.
My faith in
DVC and Disney was restored. Problems are going to occur and when they do, they need to be made right.
Thank you to everyone who helped, listened, and/or shared their experiences.
