Horrible customer service from FlySafair call center agent

The service I received from FlySafair was horrible, I contacted the customer service agent (LUCY) at 12.56pm on Monday (14 December 2020) and she was so rude on the phone, she was not helpful and accommodating to me. They refused to cancel my tickets yet I had a doctor note stating I am unfit to travel, she wanted to charge me extra for changing my flight when I didn't ask for my flight to be changed, she kept insisting that I pay extra for changes and when I asked to speak to the manager she said that she represents FlySafair and she can help me but she could even speak properly. She was so unprofessional and after asking numerous times to speak to a manager, she cut my call. #NeverFlyingWithFlySafair
