Earfun air pro 4 - one side not charging

Hi all, 

I just bought my air pro 4 recently but now I'm experiencing the left side of my air pro 4 not charging and the left side battery stucked at 10%, I tried troubleshooting it by resetting the earfun but the left side not reacting the reset which is the light flashing. I also tried charging It for 1.5hours but the left side still not charging.

Anyone experiencing same issue and where can I get solutions for this.

Thanks in advance 🥹
