Complaint Review: Yallstore ebay

I have ordered an OMRON BP652 7 Series Wrist Blood Pressure Monitor from Yallstore on September 17, 2013. I have paid the full price of the product + shipping charges (totalling $68.89) in advance to Yallstore. I have not received the product to date. I have trusted this company because it is featured on ebay, but obviously this is an unprofessional and untrustworthy company that I have been unfortunate to deal with. I have wasted a great amount of time and money and in the end I have nothing, they won't send me the product and they won't return my money.
