Reliance Fresh — Refund of my amount for which my transaction was cancelled.

Address:

Hyderabad, Andhra Pradesh, 500081

Hi, on August 31 2016, I had used my HDFC debit card to make payment at Reliance Fresh (VittalRao Nagar, Madhapur, Hyderabad, Telangana). That transaction got failed but my money(Rs.74.36) was debited.
I informed to the store manager and they told that with in 3 days my money will be refunded, till now it was not refunded/credited in to my account. Later when I went as asked the store manager about this issue he refused and responded rudely, this is shame on your part even don't know how to behave to customers.
I need my refund.
