I DID NOT GIVE CONSENT TO CDS CONSULTING

I got a call from ***. A lady spoke faintly as I couldn’t hear her voice, so I asked her to to repeat and she spoke abit louder confirming my name as I said Yes, She hung up. The next minute I got a text “I…… my name and ID number” gave consent for CDS CONSULTING PTY LTD. To do a credit report for me. This is BS. These guys are ***** and where do they get our information from
