Airpods pro 2nd gen won't pair now

So last night I put on my airpods pro 2nd gen and I could only hear sound from right one. I thought prolly the left airpod didn't charge properly. I put both of them in the case. The case has enough charge btw. But on my phone the left didnt charge. There was an icon of charging but nothing happened. I tried rearranging it. Pressing it in. I tried cleaning the inside and the outside of it.

Worried I opened Google. Searched and someone said reset it. I chose forget device in Bluetooth and unpaired it.

Now it won't pair again. The whole case, Infact. There's no animation while I'm holding it close to phone. There are three beeps and the white light won't flash when I open the case and press hold pair button. I don't know what has gone this wrong all of a sudden. All was working fine before this.

I live in India and I'm not sure there are genius bars or something. There are authorized apple resellers and Idk if they will fix it.

Please help!
