Flipkart — Refund not given even return of product is done

I reported this issue on same day when wrong product delivered. Flipkart said due to technical issue we cannot return this but trying to refund the amount. After that they said they need time 24 to 48 hrs to solve this issue. On 5th feb they emailed me regarding this matter and said to send the account details for refund and told that within 7days refund amount will come. But still nothing happen and then they show that they solve this issue form flipkart side in app.This msg appear in app. On 12th feb again I got a call from them they said within 3 days amount will come but still they are just fooling me and nothing happen. till date no refund
