Sharing personal information without consent

I got spammed by Clientele life numerous times to such an extent that i had to write a review about them. So i was contacted today by the marketing team 25/09/25. I requested that i was told where they aquired my information from as i never gave anyone consent that my details by shared. They told me they aquired my details from 3 way marketing. I tried phoning to find out where my information was aquired,but no answer from them after phoning about 6 times and being cut off...here we are!
