KZN Wildlife not refunding or taking calls

I made a booking which could not be used due to lockdown. I paid the amount in full which they said would be refunded. I had an email on 18 June 2020 to say my refund is being processed. I am still waiting. R25k! The manager is not taking any calls. I have phoned a few times since 18 June and still nothing! Unacceptable
