Was it fine when the consultant looked at it? You know, sometimes when we say there's something wrong, and it doesn't show up when someone looks at it? Like going to the car mechanic with a squeak in the car and it doesn't squeak when you're there.
Where are you? If you're in Perth, I guess you could take it to HO to show it to them. The other thing is that you can ring HO and see what they say.
Can you post photos? An inch is pretty big, so it's hard for your consultant to deny.
