7.5 hour delay on flight to DBN

To whom it my concern , <br> <br> I think I speak for myself and the other 140 people on board JE253 on the 13.02.15 to DBN . I had to wait for 7.5 hours to take off from JNB which is totally not called for . No apologies from Staff or Managers all they say is that the awaiting for feedback , the staff at the mango guest counters in JNB are so arrogant that they are taking lunch and cannot assist us , firstly was to take off at 12h00 then 14h00 then 17h10 then 17h55 , finally at 19h30 , which was not even a Mango Plane ? , we still had to buy food and drinks on board , I am not even sure food vouchers were passed out at ORT , if so not every passenger got them . The worst part of this is that Mango had other planes that took of at 14h00 to DBN , and I think 17h00 to DBN but the passengers on JE253 left behind ? . Bianca the manager at ORT for Manager Operations could not give as accurate information nor confirmation on flight departure . They didn't know what to do in a time like this ? The staff behind the counter makes you more angry as all they can say is speak to the manager \ but she is not here now she is at the gates"I mean seriously?."""
