HORRIBLE EXPERIENCE EXTREMELY DISSATISFIED!!!

I booked a flight online with mango on the 26/01/21 for 18:45 to board at O.R Tambo, the reason for my booking was my family member was unwell and I needed to be there that evening I then checked in online prior as usual, I then received a notification from mango stating my flight was delayed for and Hour and so odd minutes, I was then sorting some last minute stuff before catching a cab from Pretoria north to O.R Tambo (the distance) I arrived abit earlier on time at the airport even though the flight was delayed only to find out it WAS NOT DELAYED AND IT HAD LEFT ITS NORMAL SCHEDULED TIME!!!! ALSO I WAS NOT ALONE!!! I WAS THEN STRANDED AT THE AIRPORT UNTIL LATE THAT NIGHT WAITING FOR SOMEONE TO PICK ME UP!!! I failed to report it at mango airlines at the airport because they were closed and the call centers were not operational, however I reported this to mango airlines helpline to an operator Petunia Mthabini! Who also didn't get back to me yet with a response after me sending her proof of the fact that the flight notified me it was delayed etc... I'm extremely disappointed in this regard especially through a horrible experience like this I wouldn't want to travel with mango again!!!! EXTREMELY SAD NO APOLOGY WHAT SO EVER! NO MONEY! NO COMPENSATION FLIGHT!
