I called Environ about an ongoing rat issue in my house. I made it very clear that I was only interested in having the space under my floorboards proofed and wanted a quote. For this they said I needed to pay for a survey first which I paid upfront (stupidly!). Then the technician came round and I told him I already had rat blocker on our sewer line. At this point he had no other suggestions on what to do and left. As such I was given no quote and no survey. When I asked for the money back they flatly refused saying I'd had some invaluable advice over the phone instead and therefore they'd be keeping my money. All I got over the phone was a 5 minute call (after chasing about 10 times!) with no invaluable at all. Bascially they're only interested in easy money. I don't know of any other firms that charge for work upfront. Should have set the alarm bells ringing I guess. Avoid like the plague of rats that are still under my house!
