Pathetic service from Khulula airlines

There is never a time we used khulula and their flights were on time. My husband travels allot from durban to jhb and back. His flight was delayed from dbn to jhb by 2 hours with perfect weather and today coming back from jhb to durban it is ****** delayed again!!!! This time due to weather. So sick of this. We ****** have schedule appointments!!! If you are 2 minutes late they won't even let you in. The staff had such bad ****** attitude!!! We flippen get so hungry sitting and ****** waiting and cannot even leave the damn gate. What kind of service is this!!! Is this service free that we need to be treated this way!!!!
