StyleWe CHICV INTERNATIONAL HOLDING LIMITED Scam - resist returns - give you phony return address in China Guangzhou Guangdong

I ordered 4 dresses from StyleWe in response to a facebook ad. They arrived within 3 days. I went to return 2 of them due to fit and vendor's email response was:

"Our return center is located in Guangzhou, China. According to our return policy, customer is responsible for return shipping cost and any other related return charges (including possible custom fee). Your refund will be processed after our return center received and inspected the return package. Since International return might result in long waiting time and incur substantial return cost on your side, we recommend some alternative methods to resolve this issue. We would like to offer you 15% cash refund or 20% store credit refund (store credit offer for USD order only ) instead of returning the item(s). If there are any sizing issues, you can use this fund to alter the cloth."

I insisted on return and it took THREE EMAIL CYCLES sweetening their offer (up to 25 cents on the dollar) before they would finally give me the return address. I sent USPS and it was processed through a mail facility in China 1 week later. However after 3 months' wait, it was still not delivered.

Finally I googled the address and found that the label they gave me was to an unknown/undeliverable address.

I paid via Paypal and unfortunately they don't protect for scams like credit cards do - they just facilitate the 2 parties working it out. Vendor won't pay until I can prove it was delivered. I'm out $239.
