Earbud not Charging

Apparently my Aukey wireless earbuds (EP-T18NC) is not charging despite me trying to charge usingmultiple plugs & type-c cable.
The battery indicator diplay on the earbuds case is not lighted up either. Hence, i am unable to connect my earbuds to any mobile devices.

Hi, did you found any solution for this? With my EP-T18 I am not able to charge the box. No light in the box. The earbuds are empty after using them. Thanks
