Reliance Petroleum — Double payment debit

Address: Reliance petrol pump sardarshahar,churu,rajasthan

I paid 1020 rupees on 31 may for petrol by p.o.s. machine but the payment was failed. After that the payment was done by QR code . Sometime latter the first and second payment both debited from my bank account . I appreciate that you would solve my problem, please provide me back my 1020 rupees that was accidentally debited. Thank you .
