[Resolved]  Flipkart — FlipKart is refusing to refund when the mistake is from their end

Website:

www.flipkart.com

At first place Flipkart sent a wrong product that is rakhi set and instead of taking it back, giving force replacement. Replacement will take atleast 5 days but rakhi festival is day after tomorrow, what will I do with the replacement once the rakhi festival is over.

Have called them many times and insisted for refund (669 rps) but they are refusing for refund.
Please help me as customer always suffers.
