Stop spamming me

I am sick and tired of being spammed by info@marketing.cashandcarry.co.za. I have many times unsubscribed, but their junk keeps on coming into my mailbox. If you pay someone to manage your marketing apps and messaging, they need to get someone who can do a better job, when I click "unsubscribe" I expect the spam to stop. I will not play cleanup for this mail thrash.
