Nespresso harassment of marketing material.

I have been trying to unsubscribe from Nespresso Club since the beginning of 2025. I have clicked on their link to unsubscribe me more than 7 times that I can remember. On 22 October after emailing customer services, I received this reply "Dear Aldean , Thank you for contacting the Nespresso Club. Club Account Number:WW021544 We respectfully draw your attention to the fact that you have been successfully removed from all of our marketing communications. Please see the attached information that confirms your successful removal." The marketing emails kept on coming. On 30 October I sent a marketing email back to them to show them I am still getting their emails. Reply from them " Dear Aldean Thank you for contacting the Nespresso Club. Club Account Number:WW021544 We kindly ask you to note that we have submitted a request to our data team to guarantee your removal from all Nespresso platforms. I would like to extend my apologies for any inconvenience this may have caused."

To date I have received two more. What else must I do to stop them harassing me.!!!
