False Advertising

Woolworths new weekly deal promotions\pamphlet came out on their website for the new week dating until 4 August and their 6 pack 1-liter milk was on special for R64.99. While doing my online shopping I noticed that the milk was showing R64.99 on their pamphlet but if I go to my cart it shows the original list price of R79,99. I gave their online shopping team a call to advise them in hope of change, directed them to the online pamphlet, and the representative said that he will contact their IT department to correct the cost. Two days later and the milk list price is still showing its original list price if I go to my basket and the pamphlet is still online. Today I woke up and they have a completely new weekly pamphlet online for the week ending on the 4th of August. So they advertised falsely and no one gets back to me to even say sorry but the price was listed incorrectly. This is completely unacceptable as I have become used to Woolworths having a high standard of customer service and quality products.
