Modlily Rosegal ?, Poppoly ?,  No returns, no contacts, refusal of refund, no explaination, within 30 days, Facebook China Internet

I ordered two swimsuits because I did not know if they would fit me. The return policy on the internet is within 30 days, which I am within 30 days but Modlily is dragging their feet so it may go over 30 days. I filled out all my information on a "ticket" and they answered back "You cannot return these items". There is no way to reach this company. No phone numbers. No address. No email. They claim to pride themselves on good customer service and they will gladly refund your money if it's within 30 days, if you are not satisfied with the product. I've been had!  My order was on a credit card. I only orderred from this company because I seen the advertisement in the right column of my Facebook page for so long I figured it to be a reputable company from Facebook!
