Chinese Web Sites or on Facebook easy to spot so buyer beware.
1. No return address on the returns policy............thats because the site will look as if its in your country (where they despatch goods from) BUT they will ask for returns to go back to China (returns depot) at a shipping cost nearly always more than the item is worth. 2. No contact telephone number............if you click on contact the most you will get is webmail or an email address. 3. No company address information. 4. Great looking items at bargain prices that turn out to be tat.
HOWEVER you may still have the option to do a charge back if you funded your paypal payment via a credit card. Also Paypal may contribute towards return costs IF you have activated the below link (if available in your country). https://www.paypal.com/us/webapps/mpp/returns
