False advertising

I have been looking for the perfect gift for my wife and so I did , I walked into Sterns Centurion Mall and after browsing around found a ring of which my wife really wanted , the sales lady assisted showed us the ring my wife tries it on and loved it ,the price of the Ring was marked just over R17500 and the sales lady did not even have any effort in wanting to assist , so we left visiting a few more stores and returned viewed the ring for a second time and the lady confirms the price has been marked down from R27000 to just over R17500 the ring was even marked on the shelf for R17500 , we took a walk discussed our finances and came back for a third visit we decided to have the ring lay buyed as I needed to have funds from my fixed savings taken out and pay it off after the 7 days savings cleard , the lady who initially assisted us was busy with a customer and called a second sales lady to help Adalaide , she told Adalaide that we are here for the R17500 ring so Adalaide gets the keys gets the ring and assist with the lay buy , by then the first sales lady disappears and Adalaide goes to the back for few minutes comes back and asked for R2700 of which did not make any sense as we agreed to pay 10% and then pay the ring of in the next seven days , Adalaide then says no the Ring is actually R27000 and that someone made a mistake and there is no way that the manager Codillia will be willing to do anything about it so we can leave , we then tell her it’s not our fault we came in to purchase an item of the shelf and it was clearly marked just over R17500 she then calls Cordiallia and says we want a better price than the R27000 but does not tell her what happen she then says Codillia says no way are they going to do anything about this !!!!! Firstly this is against the consumer protection act!!!!!! Your company falsely advertised and then makes us feel unwelcome !!!!!! Your employees need to go for professional training and learn about customer relations as clearly they no nothing about This issue will not be taken lightly as I feel we have been embarrassed by your mistake and your false advertising if your company has made an error I believe that it’s your problem not ours !!!!!!!! Adalaide was not even apologetic for a second and this was the worst experience ever I’m am disgusted !!!!!!! I will report this to the CPA and I will post this all over social media and send this to the media as well !!!!!!! Sterns I have shopped at a lot of your competitors you should learn from them I would have never expected this from a strore that sells higher valued items !!!!!!!!
