Amazon India — Action against amazon for my refund

I've ordered a product on Amazon and returned due to some issues. Amazon is telling that the money is initiated back. But what ever the reference number they are giving is showing someone else's account and amount or invalid. I called to Amazon customer care support time like a 100 times since july 2022..the response of amazon customer care members to customer is wayy tooooooooo poor. They are humming songs while iam trying to explain my problem.. They are keeping call on mute for continue time and i have to disconnect out of anger. I want my refund back
