Why did you ever buy another jacket after this one? It set a bar too high.Leather jacket makers aren't necessarily tanning experts and often enough, when a leather jacket maker is introducing a new leather, they too go through the same process of trial and error, trying to find that perfect leather to work with.
If the leather seemed good and came from a somewhat respectable tannery, in all likelihood, Lewis Leathers too could not have anticipated something like this would happen so what happened to you might turn out to be as much of a shock to them as it was to you.
Which is why I'm absolutely sure they'll take care of you. LL isn't some small time cheapo scam company. Hearing about it will probably upset them even more than it did you.
The jacket that you bought is a motorcycle jacket at its core. Regardless of how it was stored, believe me when I say that this should not have happened. No way. 7 years ago I have found a motorcycle leather jacket that was buried for years under a pile of boards in an old, leaking attic. I dusted it off, cleaned it and wore it for a year. Eventually I gave it to a friend who to this day wears it on an almost daily basis and other than the usual light fading, not a single stitch on that jacket is out of place.
My Lewis Leathers Super Phantom was sitting piled up in a corner of an old, musty, stinking basement for 20 something years. When I got it, it had actual spider nests in the creases. White mold was growing all over it.
Today it looks like this...
