I had this with Radisson Edwardian in London last year. At the hotel, they next to implied I was trying to cheat them when I asked about the possibility for a late check-out based on EBG... also said there would be no points. Against my habits, I actually send a complaint to their customer service, where they apologised for the rude service etc, offered some useless compensation (like a room upgrade next time, to which I should have been entitled to anyway), and reconfirmed that only their own programme would give points (also they confused EuroBonus with something completely different, don't remember exactly what any more.)

However, after their reply, I simply sent the receipt to EB retro-claims, and within a couple of weeks, received my 2500 basic points without problem.
