Evetech warranty desception

I have bought a new lenovo laptop from evetech. The description clearly states a 3 year on site warranty from lenovo. I registered my laptop for the warranty and it stated only 1 year warranty. I contacted lenovo. They stated I need a extended warranty coupon and use it within 30 days of the laptop purchase. Evetech has not given me the coupon and states that pinnacle has my warranty. Pinnacle is the service centre and they are'n Lenovo. The description clearly states 3 year on site Lenovo warranty. As far as Lenovo is comcerned I have a 1 year warranty How many people have they conned like this?
