Hi Lenah,
I'm thinking that if you have worked with someone and your experience was less than favourable,then use the feedback facility to record this.I'm open to correction on my next quote however that feedback is only available where you have worked with someone, nevertheless it is very frustrating when time is wasted by whatever means, for all parties concerned, models, photographers, stylists etc.If in doubt, seek the advice of James, who will point you in the right direction,
Regards Wayne.
