Woolworths customer service not responding to my request

I am beyond frustrated with Woolworths customer service, who have been ignoring my emails for the 10 days. When I signed up online, I specifically unticked most of the boxes relating to promotional emails I did not want to receive. Since then I have been receiving , several times a week, messages regarding things for which I have absolutely no interest. I brought this to the attention of Woolworths Customer Service, via email, even pasting a screen shot to show that I had not ticked those boxes as well as a shot of the list all the recent emails I have received. I have had no help from them, despite sending them FIVE emails in the past 15 days, asking for someone to phone me about this, as it may be that I need to untick something further. In fact, during this period the "junk" promotions to me have increased. I spend a fair amount of money each month at Woolies and am NOT IMPRESSED.
