Terrible service

The below is an email that I sent to Mango - I still do not have feedback. At the time of writing this email to Mango, we did not know why the flight was delayed. Only after taking off, the pilot announces that the aircraft went for some engineering thing.

To whom it may concern. Kindly note that I am currently standing in a queue for more than 20 minutes waiting to board flight JE241 which was an hour delayed. This is absolutely ridiculous. Firstly the flight is delayed by an hour. Its supposed to depart at 5h55. Delayed to 6h55. I only boarded the flight now. I have an 8h00 meeting in my durban office. I am disappointed in the fact the no one comes to apologize for any inconvenience... everyone just thinks that it's ok for the flight to be delayed. To catch at flight at 5h55 I had to be up at 3h30 only to get to the airport on time and notice that the flight is delayed. I WANT TO KNOW WHAT WILL MANGO DO TO COMPENSATE FOR THIS INCONVENIENCE OTHER THAN JUST AN APOLOGY EMAIL. I IWLL GO TO HELLOPETER, SOCIAL MEDIA AND THE NEWSPAPERS. I AWAIT YOUR FEEDBACK
