False advert on the internet

I am currently booked at this hotel and have received terrible service from staff and the hotel itself,when I initially booked the hotel online I booked for breakfast as well now according to my knowledge when you book a hotel with breakfast it's a baffet which is served from early in the morning.I checked in with my 2 sons yesterday and was told at reception breakfast will be served from 6:30 in the morning,we got up this morning with my youngest who eats early to go for breakfast at 7:15 only to be told we need to order what we want and that they only start serving at 8.what happened to the 6:30 I was told about at reception and the baffet?what I booked for on the internet is false advertising they should just be specific when then room with breakfast cos right now I am seriously not happy.
