Unsolicited loyalty card preemptively delivered to my home

An unsolicited loyalty card was preemptively delivered to my home, saying I have been pre-approved for the card and need to activate it in store. I never requested this. I did not give you my details. I am registered on the National OPT OUT database. I do not have any other store cards. I consider this a violation of my privacy and the POPIA act. If I want anything from you I will initiate it personally. Please action the below asap:

1. Remove my details from any and all of your marketing lists. I am not interested in anything you have to offer. 2. Tell me where you sourced my details so I can contact them too.
