I have no idea if they lied and were just being nasty to you - but that seems unlikely. The more likely scenario is they gave that "for sale" room to a higher ranking Globalist but left it for sale until that person checked in. Another explanation is the inventory was off, and they didn't have any to sell BUT could upgrade anyone who bought the standard suite into a premium suite.
