No response to my query regarding my drake down jackets

On the 23rd of March 2017 *** and again on the 2nd October ***. The drake down jackets bought is of extremely poor quality, having it only 8 months now and only wearing it on special occassions or cold nights, our jackets are still losing feathers, and my Fiance's jacket stitching has come loose by the ribbing at the bottom. Since we have bought these jackets it has given us endless problems either our clothes are full of feathers or I have an uncomfortable stabbing in my back or somewhere else due to the feathers coming out I've recieved no response since my email
