Worst customer service!!!

Good day,<br> <br> On the 28th of December 2015 I app**** for the Samsung J5 contract with the gopro. The first thing I asked the sales lady (Amber) was whether or not they had the gopro in stock as this was the only reason that I was interested in the contract. She went to check and said they had no stock in the shop but that it has been ordered and will take a week maximum.<br> <br> I went ahead with the paperwork and my contract was approved the next day (yesterday). I went to collect my phone the same day, asking once again about the gopro, and again being assured that the gopro is on its way. <br> <br> And then this morning I get a phone call saying that unfortunately the gopro is out of stock and that the deal has ended. I went to the shop personally, where a very rude lady told me that the gopro has been out of stock for more than a week. Admitting she remembered me asking about the gopro 3 days ago, but no one had the decency to tell me then. I asked her to cancel the contract due to being **** to, but she told me that once the phone has left the shop, its impossible to do so.<br> <br> I am very upset. It was meant to be a gift for my fiance but turned into a horrible nightmare.<br> <br> Please sort this out!!!
