Useless Zando

I placed an order on the 26th of November and made a payment on the same day. My status has been on "Processed" since that day. I emailed them on the 5th of December and my order was delivered the same day. However they only sent one item. The the other item I only received a sticker of the item I purchased. I followed up and informed them of the mistake that had happened and there has been no response ever since. I cannot send the item back because on the system my order is still being processed. I'm totally disappointed. I want my money back
