Poor customer service

I was due to fly Qatar Airways on the 28 of January 2022 from Durban to Paris. The flight was supposed to leave at 19:08 pm but that never happened. All passengers were queueing at the gate waiting to board the plane but it lead up to unpleasant events. An announcement was made that the Plane was experiencing some technical problems. And so the long wait began. We waited for at least 4 hours and all we were told was the “plane had some technical problems” to a point where the announcement was halted. Passengers were unsettled I for one was super hungry and thirsty. We were not offered even a single drop of water while we waited for the technical problem to be fixed. At around 23:00 pm we were told that the flight was canceled and we would be booked into hotels for the night. We left for the hotel an hour after the announcement. We get there the hotel restaurants are closed and went to bed on empty stomachs. At 06:00 am we had to be up and running to get to the airport for specially organized flights. I have written numerous times to the so-called 5-star airline and have not received a single response or an acknowledgment of my email. When I was leaving for South Africa last I experienced some problems as well there. Still sent through a complaint and nothing from the airline. Your services are below mediocre for an airline that has claimed the 5-star spot through consecutive 3 or 4 years
