Zero effort or attempts to support when 5 mins late to check in 2 bags…

We checked in online the night before for 3 out of 4 people and couldn’t check my dad in online as he needed assistance for a wheelchair. He has stage 4 lung cancer so walking fast is not an option. Arrived 45mins before but only managed to get my Dad to the check in counter by 40mins before they closed the counter for bags to be checked in… told we could get hand luggage onto the flight but not our 2 check-in bags bcos they don’t accept any bags if it’s not 45mins before… we had to send my 17yr old daughter and Dad on the flight and pay R8k to book new return flights for the same day to get 2 of us home… no exceptions are made.. we travelled to the airport with an ETA of 90mins before our flight… but we luck should have it we got stuck behind a car towing another car, traffic and only to have a lady assisting that could help but refused to try. With no support from their WhatsApp line other than sorry about how you feel but we close 45mins before…. Never using this airline again…
