I hired a removalist company in Queensland and paid a $500 deposit. They failed to do the job and have not refunded our deposit. It's a bit complicated because they delegated our job to another company without our permission and without telling us they had done that. The company they delegated the job to stood us up on the day. They simply didn't turn up to do the removal job. We hired Company A. We paid them a deposit. They issued us with a receipt. Company A claims we have to get the deposit back from Company B because they delegated the job to them and forwarded the deposit to them. We were under the impression Company B was a contractor for Company A, not a separate entity. We did not enter into any agreement with Company B. We have not been issued a receipt from Company B. Company B was the company that stood us up on the day. We had to find other removalists on the spot, as this was an interstate move and we had to hand our rental property in that day. We ended up having to pay the replacement removalist an additional $2000 on top of the full price the first removalist was charging us, plus we've lost the $500 deposit. We live in the ACT. I want to sue them for losses (non-refunded deposit and extra costs incurred by them failing to uphold the agreement). Do I complete a Civil Dispute Application with the ACT Civil and Administration Tribunal or the ACT Office of Regulatory Services under Australian Consumer Law? I need to represent myself because I can't afford legal representation.
