Spam emails from SB without unsubscribe: webinars

I am constantly spammed with emails like this one:

April Webinar : Economic overview with Kevin Lings

These are from ********** so SB needs to take responsiblity for them. There is no unsubscribe link. You can imagine phoning support and trying to get them to stop sending unsolicited spam without unsubscribe links. I have tried to complain but no one has the agency to get unsubscribe links into these spam emails. Someone at SB has just given permission to spam their customers from their offical email address.

The reply to address is **********

IT IS ******* TO SEND UNSOLICITED EMAIL ADVERTISMENTS WITHOUT THE ABILITY TO OPT OUT. https://ispa.org.za/spam/south-african-law/

Regardless from what 'department' of SB these emails orginate, they use the official address and thus SB is *******ly spamming me. THIS IS NOT ACCEPTABLE PRACTICE.

I obviously don't want to block ********** email address. How can we get this bank to stop sending spam to customers without consent or opt out option. How can I opt out of these webinar emails?

I forwarded all 8 webinar spam emails to ********** . Still getting them.

I posted on their community forum, still getting them: https://community.standardbank.co.za/t5/General-banking/Spam-emails-from-SB-without-unsubscribe-webinars/

IT IS LITERALLY IMPOSSIBLE TO UNSUBSCRIBE FROM THESE EMAILS. THIS IS EMAIL. NEXT STEP CONSUMER COMPLAINTS COMMISION
