Is Yivette a Scam? Review of Online Store

I received shoddy copies of dresses that bore little resemblance to their marketing materials. When I insisted on returning them, Yivette then revealed I'd have to return the dresses to China at my own expense, which I did. They claim never to have received my return (which I suspect is a lie). I plan to report them to the police and I have told them this. They have given me 50% refund on the cost of the dresses but I am still €54 out of pocket and feel I have been scammed. This company is wholly fraudulent from pretending to be a company operating in Spain or UK, to the poor and fraudulent quality of the products. Avoid Yivette!
