What to do about warranty with blistering shingles

So I recently had hail damage to my garage roof. Well come to find out that it was blistering too after less than a year old. Well I have proper ridge vent venting. It doesn’t get insanely hot in my garage. I along with a knowledgeable buddy installed them. The singles themselves are GAF Royal Sovereign from Lowes. So my question is, is it even worth battling with GAF to do a warranty claim? Are they just going to deny it or give me the run around? Any advice or insight is helpful. Here is a pictures of my roof.
