State Bank Of India [SBI] — money stuck in the payment gateway

I tried to order a thing through online shopping site called flipkart, but the order was not placed but money got debited from my sbi account numbered [protected]. An amount of rs.124 was debited on 7th of april and the reference number for transaction was igafwenmx5. When i contacted the customer support of flipkart they said that the payment is still showing pending. Its been nearly a month and still i didn't get my refund and i think the money debited from my account got stuck in the payment gateway. So, i humbly request to please initiate the refund of the amount debited from my account.
Thank you.
