Pick n Pay unable to opt me out of communications

I have been trying to opt out of all communications from Pick n Pay for over a year now via opt-out links as well as contacting customer care and smart shopper. On the 21 October 2015 after many attempts Pick n Pay sent me an e-mail ensuring me that all my details have been removed from all there systems and that I would no longer get any communications.<br> Today, just over a month later, unsurprisingly I got another e-mail communication from Pick n Pay.<br> <br> I stopped used Pick n Pay online shopping many many years ago due to poor service and I've never had a smart shopper account or card. I am NOT a Pick n Pay customers, and at this rate I'll never be one again in the future.
