Hisense false advertising on Warranty for TV's

4 year warranty . I was sold a tv from Game stores and was convinced by the 4 year warranty that the Hisense products was offering. At no point was i advised that it was actually a 3 year warranty and you had to register in order to get the 4th year. i consider this as false advertising as why would a 4 year only be available once you register further more if you gifted the product to someone how would they register the product without proof of purchase ? Also how is it that a backlight would be considered a wear and tear item in a tv ? and how is the lifespan of a backlight only be 2 weeks after the 3 year warranty that is sold as a 4 year warranty ? Is this fair should Hisense not make their warranty sticker to say 3 years warranty and show on the sticker + 1 year if you resister instead on the back of the sticker as i was informed its on the back of the sticker ????? false advertising
