Poor customer service!!

Game advertised a Y11 cellphone for R320 and I went to Clearwater mall to go and buy it. To my surprise they told me it’s R2600, i immediately opened the website to show them the price and they still refused to sell it to me saying it’s the wrong price. What’s shocking is that I have proof that some customers bought it at that price today. I ll attach the screenshots taken and the receipt for the phones that were purchased at R320.
