Using "Bait & Switch" on their website.

I have found numerous examples of this company using "Bait & Switch" on their website. Many items have their prices shown as "From", but when you click on the smallest size item, the price jumps more than 50%. Example 1. From R55 jumps to R95. Example 2. From R65 jumps to R105. Example 3. From R70 jumps to R125. I brought this to their attention, but nothing has changed.
