Similar happened to me with Alberts Oz Park. Gave Rob C $800 on a Wed for work commencing Fri. Rolled up on Fri morning to a closed down store. Went straight over to Alberts Vic Park for a What The Fuck???!!! and they told me he'd fucked off over east or something cause he was in deep with someone. They carried out the work with $800 knocked off the price. I know it's not going to help your situation but I do wish you all the best with getting your money back. Or at least a cheap set of Rays
