Meta display the charger case does not charge

I have approximately 3 months with my meta display, but for a week the charger case does not charge only flashes 4 times a red light, I have tried it with different chargers, I have left it for hours charging with the lenses and without them and it always does the same, at this moment my lenses are discharged, it seems crazy but I can't find any way to communicate with meta for this, not even in the account my devices appear,
