I WANT MY MONEY BACK! KULULA IS *****ING OUR MONEY

Yesterday Kulula sent me a sms to say they have cancelled my flights, I have emailed Kulula asking to return my money back into my account. I tried calling them multiple times this morning and their line always busy, after holding for 7 minutes I got through to a “Tiffany” who told me I can get a travel credit (I am not planning on leaving cape town in the next 12 months) and when I asked for a full refund she informed me that I didn’t buy a flexi ticket!!!! Why would I buy a flexi ticket? I wasn’t planning on cancelling my flight. They are REFUSING to give me back MY MONEY. As many others I would like a full refund to be able to purchase the necessities for my family now, especially with financial situations being unstable. This is theft!!!! How can I escalate this?
