False advertising

Clicks Greenstone falsely advertises prices. I got there and they had placed a price of R29.99 on toothbrushes when I get to the till the price has quadrupled to R139. The lady at the till went there and saw the exact same thing and there were more toothbrushes on that isle at the price. Even after the two that I had takento the till. The junior manager was called, he went to the isle and put the stock which was not there then I was called to see the new stock which was not there when I came to take the toothbrushes. I asked to view the camera on the isle, there are no cameras. The manager (Kabelo Sekgalane) says that this has happened before so he is fully aware of this. Absolutely no apology from a the manager and no measures in place to avoid this.
