I recently stayed at the Delta Hotels Grand Okanagan Resort, and no points posted. After 10 days, I tried to fill out the web form for missing stay credit, but discovered that only a fraction of the Delta Hotels properties are listed in the "Hotel Name" field. Since the Okanagan Resort was not among these, I tried to type in the hotel's name without the auto-complete kicking in.

I haven't heard any acknowledgement after several days, which is unusual in my experience. I wonder if not having the hotel's name auto-complete in the relevant field causes my missing stay credit request to not go through, or automatically get rejected?

Is every Marriott flagged hotel supposed to be listed for autocompletion in the Hotel field of the missing stay form?

Have other FTers encountered this situation where the hotel they were staying in was not found when trying to fill out the missing stay form?
