Hificorp misrepresenting products in Adverts.

On the 27 January 2020 I purchased a Canon Camera online. At the time of the purchase the picture showed a camera with an additional lens and the description indicated that it included interchangeable lenses. Before I made the purchase online I called the Woodmead branch and the sales consultant confirmed that it is a camera with an extra lens however they did not have stock. I called the call centre and they confirmed that it is a camera with an extra lens. however the stock is coming directly from the warehouse hence none of the branches have the stock. I placed the order and was awaiting delivery of my order. The next day when I viewed the product online it was no longer picture of a camera with an extra lens but a camera with a memory card and camera bag. The description, however still stated "interchangeable lens" I contacted the call centre and explained the issue and that I was expecting the camera with extra lens and not a camera with a memory card and bag. I have forwarded them screenshots of the decription of the product as well as telephone recordings where their staff confirmed that it includes the extra lens which was before I placed the order. Today I get told that the picture and the description does not state an extra lens. The description states "interchangeable lens", It was confirmed 3 times by 3 different employee's of Hificorp that the product comes with an extra lens. Now Hificorp e-commerce department is disputing the purchase, even though they have 6 different recordings with 3 different employees confirming that it includes an extra lens. After 5 days it is now been regarded as an escalated complaint.
