Having been employed in the hospitality industry for years I may be able to shed some light on what may be happening here. Many time hotels will run these types of specials during their slow season in an effort to boost their occupancy; airlines & car rental companies will also do the same. Usually there are restrictions involved with these specials for example subject to availability, minimum # of nights stay, restrictions apply, one per customer etc.
The way these normally work is the hotel will set aside X number of rooms for this special rate, once these rooms are all booked our their occupancy reaches a certain percent for that time period they blackout the discounted rate as their rooms are now in a higher demand. This is what I suspect happened to you, when you called the first time the PASS special was available and your reservation was booked but by the time you called back a week later they blacked out any further special rates fro that time period. I have seen this happen in the same day on occasion when demand is high.
As for charging your debit card I suspect that there was some sort of cancellation policy that if the reservation was canceled you would be charged X night(s) stay. This is also a standard practice in many hotels. But without knowing the exact wording of their PASS promotion I can only make a guess as to what happened.
