AJ Maddah, promoter of the cancelled Soundwave festival, has continued to take no prisoners on his preferred social media battleground five days into the crisis that has rock fans wondering if they will ever see a refund.

Plenty will be wondering if Maddah has gone too far with his latest outburst on Twitter on Sunday night. Among several posts were two allegations that upped the ante in the stoush over who should pay back fans: that Ticketek (which like Eventopia is owned by TEG Live) 'advanced funds to [Soulfest] and when they cancelled you used SW ticket money to refund [Soulfest] tickets'; and that Ticketek might have falsified documents reporting Soundwave sales made to 'cover your tracks'.

There was nothing discreet or tentative about Maddah's conviction either: he included Ticketek's handle in both tweets.
