They will *SPAM* your mailbox! ****tiest marketing team on the block!

I once entered a competition on Twitter which this company hosted and I was not lucky enough to win. For the next 4 years they have been sending me newsletters non-stop. When I attempt to unsubscribe with the same email address they spammed me on, they say "email not found, send a mail to ***" for example. I've done this on three different occasions and now behold, they are spamming me again not taking hede of my request to unsubscribe. So I hope this will give their ****ty marketing team a wake-up call to do one simple thing for customer service if they even know what that is!
