False advertising

I wanted to buy a dress which was labelled R70 with a red tag, when I got to the till they told me that the marked down price is R200 and not R70. I showed the manager in charge( Rachel) that It is clearly marked R70. There was nothing that showed R200 on the tag. I even took a pictore. When I asked her where is it written R200, she couldnt show me because ot was not on the tag. I think Mr price staff members take advantage of customers especially if the mr price is in the township.
