Sir, i find that from my account rs 50000 has been paid through debit card on 15 th feb into your account. But actually i never made this transaction. I request you to please return back this amount into my sbi account no. [protected]. State bank of india, khejuria ntpc township br. Ifsc - sbin0008747
