JustFashionNow Sent clothes that were way too large and then refused to allow me to return them for correct size Internet

Before going on vacation, Irdered 3 dresses from this company and paid $18.00 to receive them before leaving.  I chose the size according to their comparative sizing for different countries. 

The order did not get delivered before I left. 

When I returned and opened the packages, all the dresses were way too large and made of super cheap fabric that probably will not survive washing. I notified Just FashionNow and they are refusing to allow me to return them for smaller size or refund my money stating I only had 15 days to accomplish this after receiving order. 

There was no number to call (just an email address) and no address for the company.  I sent emails explaining the situation and got an auto reply from them stating someone would contact me within 48 hours.  It took them 2 weeks to finally tell me that my 15 days had expired and there was nothing they could. 

Please Avoid This Company to avoid the same problems that me and plenty of other people have encountered.
