Your post makes no sense. There was no promise to the larger customer. The hotel decided to act dishonorably, that's all there is to it. As other posters have said, this is normal in Doha.

In general, service standards here are abysmal and very few people can be relied upon. People give you wrong information about everything and hardle ever do what they say they will do.

They should send everyone here working in the service sector to Malaysia to learn how to do things properly.

Just call me Tigasin. That's what I'm talking about
