Unhappy and angry

I bought 4 tickets for fuelfest johannesburg months before the event and then the event was canceled. I'm still waiting till to date for my refund.. The fuelfast informed me to email Nel Legacy Group and I did. Still no refund and not answering my mails anymore. This is a red flag for ************* companies both fuelfest and Nel Legacy Group. It was nice receiving our money and now it's difficult to refund us.
