Wellesley Inns & Suites

This is the hotel I was staying at in 2003 when, on the second day of a 3-​night stay, the maids removed my luggage from the room under the impression that I had checked out. They failed, however, to check the drawers in which I’d stored all my clothes, or the bathroom where I’d left my toiletries. However, they did remove all my food from the room’s refrigerator, and they took this and the luggage to the front desk where it was stored in a back room (where the unrefrigerated food spoiled), and where the front desk staff on duty did not at first know it was there when I came to ask about it.
Who told the maids that my room was unoccupied, and why? (My reservation was entirely in order, and so was the bill I got on checkout.) Why did they continue to think I’d checked out if I left my luggage there? If they continued to think this, why did they leave most of my belongings in the room? If the front desk staff who stored the luggage in the back room thought I’d departed and left this stuff behind, why didn’t they try to contact me? (A phone number was in their records, and on the luggage tags.) Why didn’t they inform the next front desk shift of this unresolved matter?
I asked all these questions in a letter to the manager afterwards, and received no reply. I had stayed in the hotel on several previous occasions, because it had weekly rates. But after this, I have never been back since.
