False advertising on extended warranty - Game

I bought a Lenovo laptop with a pink sticker on, confirmed by Sales assistant that it has a 2 year on site warranty, and we have to register in 7 days. Upon phoning Incredible Solutions, I was bluntly told they only cover Acer and not Lenovo. The sales lady at Game Clearwater kindly followed up and confirmed with me that the original sales assistant made a mistake to tell me to register and that I should check one of the ads. I went into the store, made the purchase and did not buy of an ad. The Lenovo box has a sticker on with GAME EXTENDED warranty, which is clearly not what they intend to offer.
