Flipkart — Refund processed by Flipkart but not credited to my bank account

Address:

67/A/2 Debendra ganguly road Flat C1 2nd floor

I have Purchased one Washing machine from FlipKart. After return they show its already been refunded by the seller on 5th Dec but i have not yet received that money on my bank account yet.
I have tried contacting flipkart customer care as well as my bank branch.
I have send the Bank statement screenshots to flipkart and all but I am still waiting no resolution yet.
I am scared I will lose my money and get scammed.
