Where did Rawson get my name and address?

Recently every owner in our complex received advertising material from Rawson with our names and addresses on the envelope. <br> <br> Since the Protection of Personal Information Act, they cannot have any information belonging to me without my permission. I have not given them my permission to keep my information on file.<br> <br> How do I ensure my details are removed from any lists/databases they have?<br> <br> <br> <br>
