Woolworths Spamming me with post

I have asked numerous times to be removed from the Woolworths postal mailing list and I have copies of communication on file. What they are doing is *******, bombastic one sided and not in line with the Poppi Act. I want to place this on record so when Woolworths gets fined by Government and people are fired as a result that they cannot say that they were not aware of it. If I ask a company in South Africa to stop sending me post, by law they are obliged to do so.
