How do you contact the manufacturer of worthington clothing?

I have purchased many pieces of Worthington clothing, and have always thought that they were all good quality, but to my disappointment, I have had several sweaters that either pilled the first or second time I washed them, or color fading on part of the sweater after 1st washing. In this day and age, we want to buy quality because we have to get the most use out of the articles of clothing that we purchase. I am struggling as to whether I should pursue buying any more of this brand. Thank You.
