Unable to unsubscribe from marketing mails

Jeez Louise, for years I've been trying to get removed from ABSA's mailing list. To date, I've escalated to the highest office, including their Information Officer and Chief Marketing Officer. I've recieved confirmation from half a dozen team members at ABSA that my address has been removed, blocked or put on a DO NOT CONTACT list. Despite this, I'm still receiving emails about Bidvest lounges at the airport and Takealot Fire Sales.

This morning, I spoke to Ansuretha Oberholzer, Head: Product Proposition, Credit Card, who said that these are regulatory emails, and suggested that I "just close your account if you're not happy to receive these emails".

-slow clap-

If this is the standard, the gap between Absa Group Limited and its competitors starts to make sense.
