Samsung Did not honor their IP67 water rating for the Galaxy S5 Active Plano Texas

I've been happily using Samsung Phones for years. I recently (in May) upgraded my phone a Note II which I really loved, to the Galaxy S5 Active. I'm an avid Kayaker and figured that the IP67 rating of the S5 was worth the smaller screen compared to the Note phone. The idea was to get the phone out of the water proof pouch I used to carry the Note in so I could use it to navigate, call for help and other fun and serious things, in a pinch 911. 

The IP67 rating I was relying on states that the phone should be, "Able to protect against Immersion up to 1 meter for 30 minutes." I was involved in some rescue practice where I was in the water 3 or 4 times for about 3 minutes each time where my phone was in my PFD (life jacket) to a depth of about one foot. Clearly this is within the bounds set by the International Electrotechnical Commission who are the people who set up the IP67 rating which Samsung says this phone complies with.

Samsung says "liquid damage" voids the warranty, but if my warranty claim is based on the phone failing the "liquid" part of the IP67 rating then by definition it would have to have liquid damage. Right? When I've pointed this out to them they have told me that I probably didn't have the cover on correctly, they said this before even seeing the phone. The phone has a safety system that tells you if you don't have the cover on right, so I know I did.

So Samsung has ruled the phone is BER which stands for beyond economic repair, and because it's sustained "liquid damage" it's not covered under warranty. To me this is a violation of their advertising, their warranty, and just fair play.
