Misleading advert

I’m so disappointed with your service, I saw this morning that you have a promotion for the Lennox corner suite online.I wanted to buy it today cash and when I called your Cornubia store I was advised that it was a mistake and it is being rectified and I must do it online and when I check online it’s not there . I’m so disappointed in your service!!! I’m NEVER using this store. You mislead your customers and display false advertising.
