Really good news...I complained on their Facebook page and as of this afternoon I got this message...
Hi Jock, apologies again for the delayed response! I have confirmed we will be offering refunds to those who are unable to make it due to COVID-19 hot spots and travel restrictions over Supercars weekend. You can currently apply for a refund, and they will be processed following the event.
Well...how good is that?
My faith is restored (well...assuming we get the money)
