Just Fashion Now Kept me waiting over a month for my order-no response on giving me a refund ! City of Industry California

I placed my initial order with Just Fashion Now on November 18, 2017. After no notiifications (as they informed me I would receive) and no shipment arrived, I finally inquired of the status of my order-a quilted coat. Eventually an email stated that the order : "may be delayed. It will be scheduled to shipped out from our warehouse in 4-6 days. I agreed to this due to holiday orders I thought they might be encountering. But weeks later, I still did not receive my shipment. So on January 1, 2018 I informed Just Fashion Now that I had not received notifications or my order and that I wanted a refund of $44.60. The next day an email informed me that my order was shipped on December 13, 2017 and the tracking number (ec-firstclass.org), that it would arrive in 10-20 business days,and an apology, etc. But I sent a reply that I still wanted a refund. Since my shipment has yet to arrive I wanted a Full, not partial refund. Since this last email to them, Just Fashion Now has not responded.
