Left earpod was not working since last week
It’s community site. You should clime warranty by contacting Soundcore support by e-mail email@example.com
But I suggest to do reset and try again before you will contact customer service
If this still fails to resolve reach out to firstname.lastname@example.org with your purchase date and serial for assistance / replacement under your warranty if they are found to be faulty.
Also depending on when you purchased them will decide if they are still under warranty or not. Wish you the best of luck. I would definitely try resetting and cleaning the charging contacts in case and on earbuds first
