Ekart Logistics — Fraudulent

I got a delivery from ekart delivery person, which I ordered from flipkart. I ordered a lehnga from flipkart on 29th January 2025, I got a message of cancelation of order on 30th January 2025 and get a refund on same day. But on 1st February 2025, when I was not in house a delivery person from ekart came to house and gave flipkart envelope whose photo attached below. Delivery person get Rupee 800 cash from my wife for this order as she was unknown that order was cancelled and I got my refund. It was a complete fraud happen with us if you can't resolve this. I will go to consumer court because I have all the evidence regarding this.
Kindly resolve this and get my money back.
