Just a thought: I had some electronics get water-damaged a few years ago. Following what I read online, I stuck it in a sealed bag of rice for a week, with some improvement, but it still didn't work.
Then I bought some silica desiccant gel (reusable, in a little metal tin), and tried putting it in a bag with that. After maybe a day (I forget exactly) it was actually working OK again. I can only assume that the silica "tries harder" than the rice does, to pull moisture from the air, and is more effective.
What I bought was like this:

After it gets wet, you can stick it in the oven to dry it out again, for re-use.
But you can also buy silica gel locally and in larger quantities from crafts stores as "flower drying" gel, such as:

Also, some all-crystal cat litter is silica gel, I believe.
No guarantees, of course, but it might be worth a shot, for ~$10, especially if the company does not want to help you.
