AirPods Not Working have tried almost everything to fix them

When I open my AirPods no light shows to see if they have charge however I have had them on charge 3 times on 3 different cables. I have then tried resetting them but using the push down technique and got to the amber but still didn’t get any improvement. I have disconnected them now from my phone to try and reconnect and they won’t find my phone at all I press the back but it goes white for a second then green and turns off. Please help what do I do
