I want my details removed from marketing and spam communication

Harassing me with marketing spam calls. I want my contact information removed from their database. I do not give consent to contact me for any sales or marketing purposes, I do not consent to keep my number on their database, nor do I consent they share my contact information to any other department or business or anyone. I demand confirmation that this has been received and confirmation that my details have been removed and will no longer be contacted. I am connected with the POPI Act and in process of taking legal action against other companies as well. There is still time to include Edgars on the list before submitting the dispute.
