False advertising and lack of customer care

<p>I went to purchase a 4in 1 doll set from pnp hyper at princess crossing. the advert said R250. </p> <p>When I got there, there was only 3 sets left, needing 2, I took them but only noticed after the I got home I was charged R299.90 each and the slip said 3in1 doll set, while the box says 4in1.</p> <p> </p> <p>I then filled in a customer care contact form explaining this on pnp's website. This was on the 17th of November, I've yet to get any response regarding this.</p>
