Where to send a compliment for a Lowe's employee?

After making a large purchase at our local Lowes, we were unable to load the item onto the truck. I went back into the store and saw a young gentleman and asked for his assistance. His name is Malachi and this is the Niagara Blvd., Amherst, NY store. He was so courteous and helpful and a great representative for the Lowes company.
