UnBranded Bedding

I am very disappointed with the product. I purchased 850 Fill Power Siberian White Goose Down, and feathers have started to come out after a couple of months. Now, feathers are escaping everywhere and poking through the cover. It's very flat and has no warmth like before. I keep coughing every night that I used this comforter because of feathers came out. I very regret that I purchase the product from UnBranded Bedding. It's very expensive product and I expected high quality that lasts longer, not like 3-4month. There is even no customer service that I can reach out to get a warranty or refund. Don't waste your money on their products.
