People giving mobile 0466 875 419 are probably identity thieves. They put letters in letterboxes or phone you and say they want to swap properties with you. They don't care if you own your property or rent it or if you live in department of housing property. Straight away report them to department of housing and your landlord and NSW Office of Fair Trading and the police. Never give them your details and never tell them if you own your home and are not renting it because that makes it easy for them to find out who you are and then steal your identity.
