Disappointed with Qatar

We get to the airport 3 hrs before our flight only to find that the flight schedule has changed and we were not informed by Qatar airlines. The lady at the check in desk was neither helpful nor friendly and told us to speak to the man a several counters down and walked away from us. When we got to the man at that counter he didn't seem to believe us and sent us to the Qatar reservation desk where we met more unfriendly staff and had to wait more than 30 minutes to be helped. A man who was booked on business class with the same problem as ours was being helped with more kindess and courtesy . Finally we were helped by being booked on another flight but we have lost a entire day and a half of planned tours i.e. a city tour of Doha which we were really looking forward to during our long transit time (now that we don't need a visa to enter Qatar ) and a boat tour of the city of Berlin which cannot be refunded. Not to mention our hotel in Berlin is also already paid for and our friends have been inconvenienced. A day and a half ****** from us and all they could sorry and thank you for your understanding. We are sorry but we don't understand how they could not have informed us. How could they have not informed us! ?? We had to find transport at our own expense to come back home and return to the airport the next day. We are very disappointed by Qatar and how we were treated. We thought you were professionals but clearly we were wrong!
