Booked a stay at this hotel and really disappointe...

Booked a stay at this hotel and really disappointed with my time here, the time allotted for booking in is clearly stated as 15:00hrs.
We arrived at 16:00hrs expecting to be allocated our room on arrival, we were informed by the reception that they are running late with the room being ready, and informed us that it will be ready in 10 minutes and gave us a complimentary drink as compensation for the room not being available one hour after check in time.
Unfortunately for us we then had to wait a further 45 minutes before our room was available, 1.75 hrs later than check in is totally unacceptable for any hotel to check guests in.
I will certainly not be coming back to this hotel again. and will probably not use the Malmaison chain of hotels again.
