Bank Of Baroda — for refund of my money 1200

Address: Jaisingh pura khor near dehli road Jaipur, Jaipur, Rajasthan, 302027

I make two transactions of 600 which are failed through phonepe but the amount is deducted from my bank account without my confirmation and bank is saying no amount has been received by them. I've talked to them again and again but no responss is coming. So i need to file a"charge dispute" on them, to get the full details.
I need bank to resolve this issue as soon as possible or i'm gonna take some legal action.
