Flight delayed 3 times in a row

I booked my flight with mango between jhb and pe. I was phoned before i even flew down to PE to tell my my flight for the return leg has been moved with 1 hour. Today work my return to jhb i get to PE airport to be told my flight has been delayed until 3. I left the airport in order to board 2 hours later. I got back to the airport 2h40pm to board, just to find out further delays until 4pm. I paid over 2000 for this ticket. Now i received a text i am only flying at 5. This is absolutely pathetic. I will aftet this experience not let anyone fly with mango. You are absolutely pathetic.
