So at the weekend I exchanged my jumbo flap that was wonky and got a perfect one however last night when I took the paper inside out I noticed that the lining is not taught against the inside of the bag, it has a few wrinkles at the bottom and I can actually grab it and pull it away from the bag. What should I do? Nowhere has them in stock in London and the new double flaps are coming in. The bag that was wonky has a taught inside as have all other bags whereas this one is not attached at all. Any ideas?
