I purchased 5 pieces of these shades. Was very happy when I hired professional to install. They only worked up and down for first few months. By December the material( that holds the up down strings in place from the back disintegrated  crumbled so now they hang tenuously and lopsided. From outside make my house look terrible. I had to leave on trip out of country and hoped to address this defective product complaint with Wayfair  on my return. But I’m stuck because of COVID travel restrictions and won’t be back for awhile still. If I could give this product 5 negative stars I would. You have sold me 500 of  a very defective and bad quality product! I have a relative looking after my home. Can you do anything to make good I am extremely dissatisfied. I would be happy to have my relative send you the pictures. How shall I do this so the pictures will be joined to this complaint Do you have email I really expect an action on part of wayfair. To make this right .
