Some real estate dickhead just rang my mobile (which is not advertised anywhere) saying they were "just in the area" and wanted to do an appraisal on a house we own in <suburb name>.

It's an agency we don't use for any purpose, have never used for any purpose, and have never approached for any reason.

Is there some sort of legal issue with some smarmy sales knob looking up property owner details and cold calling them?

Makes me feel all gross that their grubby mitts are pawing through my deets somewhere in the hope of being able to stick a tongue up my bum and get a taste of some back door cash.
