archer, as i said in my previous reply, its not that they dont pass on their leads fairly, its that they barely get any leads at all. when they do get a lead, they give the phone number of the 3 window cleaners closest to the customer. so even when they pass your details on they may not ring you cos they ring one of the other two.
they post in the magazine and in the yearly newletter what postcodes they have had enquiries from, so you should check that and if your post codes covered comes up then give them a call
