POPI act......?

To whome it may concern, please disregard my previous complaint. As now the Pick n Pay driver is harassing me every afternoon calling me on my cell phone asking IF I AM HOME....? Why will you give my personal details to any one? This guy has my number and know's where I live. Should he call me again I will take this to the police. As I work alot away from home and it is now dangerous for my wife to be alone at our own home.
