I was purchasing a product off a website and the product only had one in stock, but it turns out the product was already sold and the product had still been up for quite some time after the purchase, and after i tried to purchase it the company told me it had already been sold i had actually brought a similar product that was advertised as the product i wanted to purchase. so i was just wandering if this is coincided illegal or if there is anything that can be done? thanks
