Flipkart Pvt Ltd — amount not credited to my account

Address:

756164

I had purchased some items from flipkart through pay later option which suppose to pay before 10th of next month. On 9th i paid that amount of rs.4266/- and that transaction declined and amount debited from my account again on 10th i paid that same amount successfully.
When i talked to bank about that failed one they told me that amount already credited to flipkart on 9th.
After several calls to flipkart from 16th onward, they just giving dates but still the matter not solved.
Please help
