Ordered blackout curtains they arrived and I sent them to have them shortened cost £50. Put them up and the first time we closed them was when the grandson stayed over so still day light at bed time. I complained that there were several places were small amounts of light came in. I contacted Duel customer service they did offer to replace them or refund if I sent them back I explained that I would rather a part refund as I had no curtains to put back up and I had paid to have them shortened. Was offered 20% refund and no more. Had me over a barrel as I need curtains at the window and did not want to pay another £50 to have replacements shortend
