Dell XPS 13 7390 Fan Grinding Noise / No Repair Possible / Refund?

I had my Dell XPS 13 7390 for just 3 months before the fan would start making an insanely annoying grinding sound like an electric razor. Here is a recording of the sound: https://voca.ro/gmotQvG2Pqx

It's gotten worse over the past month, but I'm still unable to get it repaired due to my situation:

The device was purchased in the US, but I now live in Tokyo. When I spoke to US Dell Support, they told me to transfer ownership to Japan, thus transferring the warranty. I did as instructed and contacted Dell Japan. Initially they seemed to process my request for repair, but then I received a phone call stating that because my device was purchased in the US, they wouldn't be able to repair it.

I relayed this information to the email provided in the log of my communication with US Dell Support (the support site now redirects me to international/Japan support because my device is now registered there), but have been ignored for over a week.

Am I just screwed because Dell Japan can't service a Dell product purchased outside of the country? I use the laptop all day for work during the current global pandemic, and the noise is driving me absolutely insane, not to mention the potential for continued damage. I am beyond frustrated with the noise and the runaround I'm getting from support. I expect at least the bare minimum of service for a faulty device at this price. If I'm unable to have the device repaired, at the very least I'd like some way to obtain a refund.

Is there any way someone can help me with this situation?
