naturally it would cost money!

I suppose if it were a British company you could try contacting a paper or investigative TV show. If they're calling your number, they're probably calling other numbers & annoying other folks, maybe that's an option (& it could even get you good publicity & more work!)

A proper, business-like company would not aggrevate customers & potential customers by continually making rude calls. Old marketing practice was 1 complaint = 10 or 20 unhappy customers. The oz consumer's association looks into bad behaviour of companies (tho usually for unhappy customers) & also into industry practices, so maybe yours might have info.

good luck
