Ekart Logistics — Fraud parcel delivered by Ekart

Today, I got a delivery from Ekart logistics of Rs.709 which I had not ordered. It was a cash on delivery product from www.parcelx.in with the tracking Id - IOIC[protected]. I mistakenly accepted the fraud parcel and had to pay the amount via Gpay. Please find attached the payment receipt and delivery update message snip from Ekart.
(Recently I had ordered an item from flipkart worth Rs.709. Hence, I thought this was the item ordered by me. After unboxing the package I realised that this is a fraud parcel pretending to be the item ordered by me from Flipkart.)
I tried reaching Ekart logistics using the contact number and email address available in the internet. However, nothing seems to be valid.
I would request to return the parcel and refund my amount asap.
