Unable to unsubscribe from marketing emails

I started using huel about six months ago on a subscription basis. I received my first marketing email afterwards like every company sends as soon as they have your email. Obviously I clicked unsubscribe because they are a cancer to my email account. And then I got another one, and another. I contacted your help desk, it did not work. Even while I was sending emails back and forth I was still getting the regular marketing emails. For anyone that has the same issue as this, it is clear that either they have no idea how to work their system, or they don’t care. Either way, cut your losses.
