Dear ABC Seamless, last week a young employee of yours was sent to our home to replace all our windows. In the course of his work it was necessary for him to make many trips through all rooms in the house. Although I don't know his name I commend him for his professional manner, unobtrusive presence, loyalty to his company, & politeness to us. When the windows were all installed he washed & cleaned all the areas in which he had worked. Whenever I see the name ABC Seamless I will think of the fine representative of your company. I hope you will commend him for me. Thank You.
