Contravening the POPPI act

I am tired of your rude sales spam calls!. Your consultants are constantly calling, i have requested on numerous occasion to stop the spam calls. I have asked to speak to a manager, and the consultant just hangs up the phone. The Poppi act prohibits unsolicited direct marketing, which you have no problem ignoring! This is not ok, and needs to stop! I do not require the use of your pathetic systems, as I already have tracking in my vehicle with a leading company.
