False advertising on their website (Builders Warehouse)

False advertising on their website. I searched for a ratchet set and came across one on their website. This item was priced at R16 (Product id: 686567). I then went into the store to purchase one. They told me they were out of stock but they can try and get one. They also mentioned that the price does not look correct and i agreed. I received a call later saying that they can order me one but i will have to pay R1700. I have all the screenshots of this price ,time and date. I have also notified them about other items and prices on their website which they have now rectified. My next step will be exposing them on twitter.
