On June 23rd 2022, there was an unnamed 23 year old male attacked on a street in Melbourne by a gang with machetes, Industrial Radio are based in Melbourne I believe, so the story is possible.
Either way, if I was in your situation I'd have called time on this month's ago.
I had a very similar situation with Letts Basses, I had to issue a Letter Before Action for them to actually respond and agree a resolution before being taken to court.
It's a sorry situation when a business just doesn't respond for months and months, it's entirely unacceptable, emails take seconds to send.
Call time, get your money back and treat yourself to something else!
