Disgusting service and treatment towards customers

It was my mothers 60th Birthday and she had booked a flight to George for the weekend. Tried to check in and the counter was closed and they refused to help her. She was still 40 minutes early. She had to re-book a flight and spend 10 hours at the airport on her birthday, the flight cost her an extra 4500 for 2 persons one way to George. They were rude and refused to help - on her birthday! She had a return flight on the Sunday and no one told her that this flight was cancelled because she missed her flight going down. So on Sunday night - she had to try to find a return flight from George and cost another 4500 - Kulula.com refused to help her. This is appalling service and has cost her so much extra money. No communication was given that the return flight would be cancelled ! How disgusting to treat customers this way. We will take this forward and demand a refund for the flight.
