I bought a Wanhe water heater in Longhua RT Mart. The merchant said that the warranty period is three years, but the warranty card is only one year. There is no warranty period on the invoice. What if there are no vouchers after that year? That's a lie. You haven't discussed it. Go to the seller and ask him to fill in the three-year warranty on the warranty card and stamp Wanhe on it. You can also call Wanhe after-sales to ask if there is a three-year warranty. /If not, it means that you are suspected of cheating and ask to quit the plane! (Legally, it's only valid in black and white, and Wanhe won't admit it if he stamps the mall, because if it's really repaired, after the sale, he will definitely say that you went to the stamped store, and then you have nothing to say.). Brothers strike while the iron is hot, they won't admit it for a long time, remember it seriously!
