I left this today on their contact form after getting one too many of their stupid spams.

Your fucking awful coffee fucking sucks and your shitty persistent marketing practices are loathsome in the extreme. Please switch to another line of business so that the human race no longer has to suffer from your abuses against our palates and sensibilities. Sincerely, a marketing professional with over a decade of experience, who hates the garbage you peddle and the way that you peddle it.
