Kemioon — order is fake

I had received an order from kemioon, which i didn't place.
I received it from bluedart with cod option and i was forced to pay the amount to bluedart as it is demanded as cod. We are unable to contact the website/sender as the website/contact details which they shared on the package are fake.
Please provide us the way to get the refund/return of the same.
