I sympathise. It's par for the course.
Had the same problem with RBs - loads of bids from fat munters despite specifying slim (size 8 or 10) and attractive. I also add no one with zero feedback, and what to you get? Porkers over 30 or 40, with zerofeedback, a face for radio and an arse the size of a small country.
I've given up with RBs, make my own decisions, often based on positive comments on here, and then only have myself to blame if it goes tits up.
