POPIA Breach

I received a call from this company. I then told the lady I am not interested but I later received a sms saying I consented for my credit profile to be checked. I never consented to anything. The SMS even came a few minutes after the call was dropped. I phoned them to find out a receptionist answered saying if I received a SMS that means I consented after telling her I did not. How is me telling you I'm not interested the same as me giving consent? which means their sales reps are chasing stats instead of being truthful, they can't even transfer you through to the relevant people or department.
