Hello,Thank you for your message. Do you have a BMT Micro order number? What is the "136 mailbox" that you speak of? We do not sell directly on Taobao, so that order ID number does not really help us identify your purchase. I tried searching under your email kelilaode28@163.com, but could not find anything.Please provide more information.Thanks,----BMT Micro, Inc Customer Servicecservice@bmtmicro.com910-792-1889 Faxhttp://www.bmtmicro.comhttp://www.bmtmicro-info.com
