I never got past the enquiry process.
They had a trip on their website that I wanted a price for as a single traveller and provided the dates. They didn't seem to be able to price it, even though it was priced on their website (for 4 people). All they kept asking was "what was my maximum budget". Eventually, when I asserted that I wanted a price for what I'd already asked for, and nothing more, and I would determine if it was what I considered value, they stopped responding. I got a very bad feeling about their honestly and would not trust this organisation, and ask everyone else to be very wary of them. Update as requested - It was the (at the time) Amazon, Pantanal & Iguazu Falls Tour, and I was dealing with a guy called Nicolas Samuel (Nico) the Director. I still have the email trail under my other email account. It was definitely this company, I can tell by the logo.
