Hi i have recently been stung by these same people. Same story as everyone else. Their new trading name for me in sydney isnt PCAA, Dales or Walker Thompson, they've changed it again.. now its Sage Sentinel Pty Ltd.
They wont give my money back either, however since their office is only in Newcastle (apparently). If i cant get this sorted; im going for a trip.
This company reminds of that Ben Affleck movie "The Boiler Room" and they need to be exposed.
I have made afew calls, and posted afew things, but upon researching on another site a lady called Rebecca left this number in her blog (some sort of refund investigator) 1300 550 475. otherwise asic, accc, fair trading, a current affair will be next if i have to.
PS. Here is there new phone number and address, incase anyone wants to do some cold calling themselves.
Sage Sentinel Pty Ltd
Level 1, 19 Darby Street, Newcastle NSW 2300
1300761124
