incommunicado, you have not got stuff you can not sell, at least I very much doubt it. You have stuff you can not sell for what you paid for them. Your loss is $1,750 less the amount you can actually get back. Your gain is one heck of a good lesson about doing your homework. I take on board that supplier is not someone to do business with, but there is a place, a way and a tone to tell us in.
Delboycorp, are these unbrandeds genuine unbranded/unknown brand rather than copies? If so, is full tech spec available? Phones only or can you get laptops? If laptops, would that include tablets? I may be interested.
This is a bit OT, so please PM or start a new thread to say what you can do.
