Asurion Walmart Product Care Plan 3 year warranty is not an extended warranty as the Walmart cashier told us sterling virginia

We purchased a new TV at Walmart in 2015. Of course the cashier wants to sell the extra warranty and tells us this covers the product beyond the manufacturer warranty. We buy the 3 year warranty thinking this covers over and above the warranty for 3 extra years. When the TV quits 3 years and 2 months later we were under the impression the first year was the manufacturer warranty and then we have 3 more years that we purchased. Called Asurion and they said the coverage begins the day we bought it. We said yes ok but that first year is the company's warranty and we bought 3 years beyond that. They said sorry but it begins on the day we bought it and 3 years has passed. We said but we can't buy a 3 year warrant later and had to buy it when we bought the TV so the first year was covered by the company and we have 3 more years afterward. No they said it starts the first day and goes only 3 years. We told them so this is only a 2 year warranty then--why does it say 3 years as this runs at the same time as the company's warranty? They will not fix the TV under their "3 Year Warranty". We have bought insurance at Harbor Freight and it goes beyond the manufacturer warranty by the stated amount and they do cover their warranty as stated. Asurion will not. So beware this is not an "EXTENDED" warranty for the time period after the regular warranty expires.
