Bad Service - It is actually a compliment when I say Mango gives Bad Service!!

Flight JE174 on Thursday 18 October 2018 was delayed for 3 hours. Mango or their staff did not keep us informed throughout this process. Later learned the aircraft was faulty and had to wait to be placed on another aircraft they had to clean. Staff made the comment that this aircrafts problem started at 12h00 the afternoon and snowballed for the rest of the day. We flew after 23h00 and we arrived at our destination in Pretoria after 02h30 in the morning. Had to be up again at 06h00 to be in time for meetings. The whole weekend was a disaster because of the amount of sleep on Thursday night/Friday morning. Mango send an apology SMS on Friday 19 October indicating they would like to offer a voucher for the inconvenience. When I phone the call center a few days later I was informed that I have a redeemable voucher of R250 on my next Mango flight. Ridiculous!! The call center operator indicated during our conversation that Mango’s flight is always on time, pathetic if the call center operators can be so *********. I will never again make use of Mango Airlines!!
