Pink Queen Pink Queen said they did not receive my return and kept my money Internet

I purchased a denim jacket through the Amazon web site from Pink Queen. After it arrived, I realized that it was too small. After contacting Pink Queen, they asked me to keep it and they would refund 50% of the purchase price. As the quality was poor this was not an option for me. I printed the return slip and enclosed it within the package, paid for the return postage and sent it off to the company. After about a three weeks I checked on the status of the return and they kept saying that they never received it. It is now 4 months since the original purchase and I am still without a refund. To make matters worse as I am an Amazon prime member I thought that I would be protected.To my dismay amazon took the vendors word that they never received it and now I am out the purchase price and the shipping cost. Do not buy from this vendor even if you purchase it from Amazon. You are throwing your money away.
