Query: Buy New Not Refurb

I made mistake of ordering refurb and box was full of fuzz & junk but no instructions of any kind of how to operate. I'm having trouble getting it to work with limited knowledge of how to use one. Be sure to see what's in box before ordering one. I should not have been so trusting that everything needed and instructions were included. Very disappointed that Amazon would be selling anything thru them like this.
