You need to contact the directories that have your number listed such as http://www.startlocal.com.au/industrial/electricalcontractorsconsultants/wa_bunburyandsouthwest/Gbj_Systems_Pty_Ltd_2113697.html

This database (reverseaustralia.com) is not responsible for them.

I suggest doing a Google search of your phone number and seeing where your number comes up under the GBJ Systems name and contacting each directory, or just contacting GBJ Systems directly and asking them to update their listings on all these directories.

To whom it may concern,

my number gets displayed for GBJ Systems and I get calls for their business. I do not own this business neither do I know who they are, please remove it.

Thank you
