So finally after insisting and complaining again (since I meeet all the criterias ) - I simply got today an answer "we will credit your points" - and it was already credited in full.

Seems they took time to actually read my request this time.

Anyway, very poor customer service for a lifetime member - glad I moved my business to Hyatt.

And yes agree - design hotels is a chain that does not make sense at all. Luxurious to crappy , all in there.
