How does servicehaircom evaluate Haier?

Haier has always been used in our family, which is quite good. I bought an electric water heater today. Haier's products are very good, but the salesman's attitude is not very good. He promised you everything when he didn't pay the money, saying that he could install it today and help me punch two holes in the towel rack, but I left less than 10 minutes after I paid the money. I called to say that I couldn't install it today, and there was no decorator. Later, I said towel. They are only responsible for installing water heaters, saying that they should pay for the materials for decoration. They are very headache, honest and unhappy. They look like they didn't pay, but they look like they paid. I can't take it anymore. Now I pay for the installation of the water heater myself. The water heater hasn't arrived yet, which hurts my nerves. They all stressed that I could help me install it today, but I won't be free tomorrow, but after I bought it, it was different from what I promised before I paid the money.
