Marketing nuisance

Marketing nuisance! After repeated sales calls I have asked not to be called again, blocked your number but you employ pesky sales tactics to avoid this and still call. How do I get removed from your sales list!? I get called every 2 weeks roughly.

According to the POPI act marketing is opt-in only meaning I did not opt in so you should NOT be calling me. While I had an account with you previously, I am not an existing customer! You should not have my contact details.
