Waited 20 mins in Doors and Windows for help on purchasing and delivering a product to my house. Walked around another 10 mins only to be told to go back to Doors and Windows and ring a bell?! What bell? Finally left and went to Home Depot in Fontana where I was greeted by employees asking me what I need and giving me the help I couldn't get at Lowe's. Customer service is the biggest single factor in customers buying and returning to a store. Without it you will continue to lose revenue and customers (like me).
