State Bank Of India [SBI] — Did not receive refund for transaction id 7005045

Address: Tumkur, Karnataka, 572103

I had return a flight ticket booked from indigo official site. The airlines have initiated the refund from their side and have provided the transaction id 7005045. The refund was initiated about 15 days back but the refund amount 5039 rs is not reflecting in the account. Please process my refunds as soon as possible or enlighten me with a procedure so i can do it.
