Kulula apathy

On Friday the 23rd Feb I flew from lanseria to KZN, besides the fact that my flight was delayed by 1hr and a half and inconvenienced my mother (who was fetching me from the south coast) the ground staff were incredibly rude and unhelpful. I left this as I thought perhaps they were irritated to have to work later than usual. My flight home was MN540 meant to depart at 21:50 - the flight was yet again delayed this time to 1:30am. I am a single woman and had to get my car and drive home at 2:30 in the morning alone! I bumped into a friend travelling on the same flight back to jhb during the following week - she told me she had received a voucher for her next travel from kulula. I had reached out to kulula in Facebook to express my distress and inconvenience only to be told I need to contact another email address and tell my story - which I did with NO response let alone a voucher! I was inconvenienced twice in one weekend yet I received nothing? I feel this is inconsistent and really apathetic! I work for a large corporate and am happy to motivate for further work travels that out company refrain from supporting a company that offer customer service such as kulula!!! I have now given kulula a week to get hold of me - in case my expectations were too high of a fast turn around call. Please could anyone advise.
