Instaticket SA totally unresponsive!

I purchased a ticket via the Instaticket website on 13 July 2019. I paid for it, and the money was debited from my account. Subsequently, I was alerted by media reports that tickets sales would only happen in Sept 2019, and people / companies who sold such tickets for the Match for Africa tennis event in Cape Town in Feb 2020, was doing so *******ly. I have emailed Instaticket on more than 1 occasion. My son in-law also did. They are just not responding to email communication and I am out of pocket. Let me just say it was not a small amount either. I just really have run out of words and actions on what to do about this situation. Not sure if anyone from Instaticket will respond to this or if anyone else had a similar experience. There is no telephone contact number on their web site. Now I understand official tickets will be sold by Computicket. Where does that leave me now?
