Right earbud won't charge - Case won't hard reset

Hi,

My right earbud won't charge anymore.

I tried several times to charge it and while the case is fully charged, left earbud is fully charged, the right one says battery is 10% then that battery is low and turns off.

I cleaned the earbud and case connectors, did a soft reset. Didn't work.

Tried a hard-reset and found out that step 2 "Press and hold the case button until the case LED starts blinking white" wouldn't work for me either ... The led never starts blinking, regardless of how long I hold the button.

Not sure if these problems come come from the earbud or case or both but definitely not acceptable for a $180 product less than 10 months old.
