Unprofessional rude without care Uganda airlines and its Johannesburg manager

no communication the flight wS delayed for over 11hrs.Monika apparently she is the manager no communication skills very rude with don't care attitude. she said it's our choice to sleep on the steel bunks or sit without any compassion. since we were at the airport in the morning being taken from Gate 11,to Gate 5 to Gate 19 ,to Gate21 than the flight was canceled.already it was after 23hrs.they didn't care whether we need to refresh or ask about our welfare.that was when the suppose manager came with an attitude of choice to sleep on steel bunk or sit on them it our choice. she was not sure about departure time maybe 3am or 5am due to technical problems. She was happy to go to her house to sleep on a comfortable bed.
