Right earbud will not charge

My right earbud won’t charge although the case is fully charged .
I have tried cleaning them and resetting the case many times . I have also tried resetting the pins as well .
They do connect but with very low charge

Unfortunately , I am unable to contact the customer service here in Egypt as there is no phone number to schedule an appointment .
The warranty has expired since I bought them on 10/3/2023

Any clues ?

I jab the same problem. The right ear bud is not touching the charging connectors. Take a piece of tape AMF put it on the lid right above the ear bud. Dies not have to be thick. Just one piece. God luck
