I was told the new charge was because the binoculars "had been immersed in water." ABSOLUTELY NOT TRUE!!! Never even used in the rain.
Sounds like Canon are running Apple's "water damaged" scam.
Tell them to keep the binos, then claim from your household insurance which should cover this evident "accidental damage" which Canon can presumably prove.
P.s Welcome to the forum. Ignore some of the daft comments above, they're not representative of most forum members.
Happy birding.
