I have worked for the company as a sole trader and they have not paid my last month money. I have found they did same to some other people as well. its not a big amount but I do not want to let it go. as they are keep doing this. I have found this company submitted voluntary deregistration in ASIC and I know they open a new company under another name. So I have talked to a Fair work legal adviser and he advised me to send them a demand letter. I did send the letter and did not get my money yet. when I ask money he sent me a message saying if you call me again, you will not see the payment. what are the option that I can take against this guy. not just to recover my money, to help others to not to get involve with this guy.
