Aliexpress No refund after order was frozen Internet

On July 22, 2015 I placed and order on aliexpress order #68294707971564 a few days later after I paid for the item, I recieve a message that stated my order had been frozen due to suspicious  seller activity and if the seller doesn't respond in 3 business days, I will recieve a full refund, and could take up to 15 business days for the case to be resolved.

Today is January 24,2016 and I havn't recieved my refund yet!! I have spoken to several people on chat and email promising I will get my refund back it has been 6 months and I haven't got nothing they won't answer my email or anything. even though it wasn't much but still they have stolen my money. what should I do next, who do I contact because I want and need  my money!!
