Air Mauritius DISGUSTING AIRLINE!

I flew to Mauritius in December last year on holiday (29/12/2017) flight no. MK0950 and flew back to Johannesburg on 06/01/2018 (flight no. MK0851). The flight back on Air Mauritius back to Jhb was the worst experience i have ever had in my life. I WILL NEVER FLY AIR MAURITIUS EVER AGAIN. We were served our lunch and i went to use the toilet shortly afterwards and while i was in the lavatory the captain announced, "will all passsengers return to their seats as we were about to hit quite a bit of turbulance. The next thing, one of the flight attendants (a male voice) started knocking on the lavatory door with such force shouting, "get back to your seat" and almost knocking the door down. When i returned to my seat i did not see or know which flight attendant it was that shouted and knocked on the lavatory door but told my husband about the incident and was very angry, upset and completely shocked by the behaviour of this flight attendant. I understand it's for safety reasons but the way in which this flight attendant behaved was totally unnaceptable and he could have just said, "Mam/Sir please return to your seat" but it was like he wanted to bash the lavotory door down. I was extremely upset after this and told my husband we hare never flying Air Mauritius again. I am a Kestrel Flyer and i have since cut up our cards as we will never be flying Air Mauritius again.
