Union Bank Of India — transaction failed but money debited from account.

I made a online bill payment for my landline through freecharge app & the transaction failed but shockingly the money was debited from my account. I tried contacting freecharge and they told that transaction failed from their end & to contact the concerned bank. It has been more than one month since the money has been debited from my account. Kindly resolve the complaint and refund my money asap. My union bank account no is [protected].

I have also attached all relevant documents the transaction was dated 29/06/2017 the money debited was 1137 rs.
