It's not good seller. I see this seller face back it not good. 3 weeks now i didn't receive the blender, i need my money back with interest, because its take  long , thank you

adding to the advice already given -

Exactly when did you purchase the item?

you say the sellers feedback [face back] is not good and its worth remembering others check buyers feedback profile and your massive number of bid retraction will cause sellers to b,lock you.
