False Advertizing

Their website states that a Finger Wave Pixie - Natural Colour is R500. I sent a friend of mine to go buy it for me and she was told its R650. She called me while at the shop and they told me its R650 I regard this as false advertising as their price is different from what their website says.

They told me to check facebooka nd I told them I rely on their site not facebook, what if I didn't have a facebook account.
