Misleading prices

<p>The store put up an adverti*****t on OLX about their cheap prices in cellphones and other electronics. They were selling an iphone 7 plus which was on promotion for R6000. I then thought it was a bargain and proceeded to make a purchase on their online store. when it was time to deliver my product to me they claimed i owed them an Additional R6000 because the actual price of the phone is R12000 or i can purchase two other items from their store at a value exceeding R6000 and I will get the phone for R6000. I then complained about this and asked for a refund. they then said that they charge 20% for a refund and i must pay R1200 in order to recieve a refund. this information is nowhere to be found on their website or in fine print. they ripped me off and put me in a tight spot where they made money anyway. This is *********. Now they are refusing to pay me back my money they are demanding more money from me. someone please help me get my refund</p>
