blankterrmall.com review: No info and seller suddenly stopped to reply

I purchased slimming mask and cream from the website www.blankterrmall.com. I sent several emails to the seller and he replied very quickly, but after I placed the order and paid for it, the seller didn’t provide any confirmation info as well as he stopped to reply. I sent multiple emails, but no response. I have no idea what to do now. Maybe someone has any idea how to track this seller and return money back, please contact me then or leave a comment. Thanks.
