I paid for this order.Flipkart is not taking any actions, they delay the refund everyday and have'nt even initiated the refund process.
Kindly help me get my money back and take action against this frauds.
Aslo order was cancelled without my consent, why take order when you cant deliver and if you cancel atleast give the money back.
No satisfactory reson was being provided for order cancellation, this seller delivers to my adress.
