Pam Golding Properties - Misleading advertising

Pam Golding Properties advertises properties on Property24 that are not on the market and are not for sale. I have contacted both Pam Golding Properties and Property24 to advise them and they both refused to remove the advert. If this continues the the Advertising Standards Authority must be informed as this also presents a security risk for owners. I have also spoken to a number of agents in the area and they are aware of this behaviour which we are only aware of in the Oaklands, Norwood, Melrose Arch, Abbotsford areas.
