Trendsi: Fashion Dropshipping

I placed my first order on Trendsi from my Shopify account, and Tendsi has not received the order. I then placed a second order, and again they have not received the order. So their order sync doesnt work1 Then they ask me for a million screenshots, like i must do all the work when their system is at fault. If orders dont sync to them, whats the use of this app? Also just found out their prices dont update either. Quite useless actually!!!
