Replying to Dalbello warantee is a joke

I just received word that Dalbello will not warranty my Krypton Rampages (that were still under the one year warranty when I sent them in June) because of "overuse".  They said that because I had used them too much they were not responsible for the liner that split down the seam leaving the boots worthless.  Its a one year warranty not a 30 use warrantee. Plus, how can they accurately tell how much I used them, the plastic was a little worn down, but there isn't exactly a science to that.
