When I purchased these sheets a year ago, I was looking for very high quality merchandise. I don't mind the stiffness of the fabric because I expect it to soften with washings. What I can't deal with is the fact that they shrink with evey washing even though I follow washing instructions to the letter. After one year, I cannot stretch them to fit the bed. This morning the corner seam split. I'd like a refund or credit for this product. How can I get my money back?
