Clicks did not apply the amount they showed on the product.

Is Clicks a bunch of *****sters? As a customer, I expect to pay the price you said the product is and trust that you will be honest enough to apply the relevant discounts. But not Clicks Comaro Crossing. I bought Dove Soap x 3 that was supposed to be R180 for 3. I get home and the slip says R254. Now I live a good 15km away from there and cannot travel just to get a refund. What must happen?
