Kulula flights - bad service and lies

I had flights booked for the 24 November 2021 and return on to return on 27th November 2021

I had a medical certificate from my GP as its a covid related issue and when i called to transfer my ticket to a travel bank or change the dates i was told by an agent(Zandile boya) i cannot do that and then she put me on hold when i got abit upset , she had spoken to her manager (Corin Peterson) and i was put on hold times through the painful call as i was told that i would have to pay cancellation fees and if change im air fairs (change in air fairs is understandble) but this goes against whats published on their wesbite . They contradict whats being posted on their site by telling me that i need to pay a cancellation fee . When the matter is covid related .

And then i was told eventually by the agent over a recorded line that i could get my tickets into a travel bank but it would take 6 to 8 weeks.

So i then agreed .

The agent then calls me back minutes later to say that her manager says that only if covid positive then only can i get my tickets into a travel bank

I then told the agent , i want what was promised and i was a recorded call and if i could have a copy of my call and i was denied that . I then told the agent to call me at 4.30 to discuss as i had to rush off and she said she will call me at 4.15pm . The agent was fully aware of what was discussed and she has not contacted me as yet .

My question is , how many other people has this happen too ? False advertising and extra charges for change in flights.

********* business practices and inadequate staff
