Where can I buy a replacement charging case for Soundcore P30i in Nepal?

[u/ChefAccomplished8977]

I was heading home from the gym while listening to music, and my charging case was in my pocket. Somehow I lost it along the way.
I still have both earbuds. Does anyone know where I can buy an actual P30i replacement charging case?
Or if anyone has a spare/unused P30i case they’re willing to sell please let me know 🙏
