Addict Gear Purchase was successful but order never arrived Internet

I purchased a pair of FUROSHI Wrapping Shoes advertised by a facebook add.

The order process and purchase went seamless, my credit card was charged with the correct amount of money. After a little bit more than two weeks I requested a status update and several days later was told that the order got shipped and that it therefore was not the sellers responsibility anymore. Any further requests for a status update and money refund kept unanswered. At this point even the shop address addictgear.com is not reachable anymore.

The order hasn't been delivered to this date.
