Myntra.com — Order delivered in wrong address

Address:

17 Muchimahal Kamarpara Manirampur Barrackpore Kolkata-700120, opposite Safar bazar Kashinath Mandir

I have not received my last order but it is showing delivered. When I called the delivery person, he told he delivered it to a wrong address my mistake and he will manage to take the parcel from that address. I still have not received any order. I want my refund as soon as possible.
