Xonight E-commerce — Received wrong product

I have ordered realme 12 plus pro 12 + 256 gb and the product which I have recieved was realme 12 plus 8 + 256 gb. I have paid 27000/- and the product which I recieved was wrong & it costs near 18000/- . Also the invoice is also wrong it's seems to be fake invoice which show IMEI number is given [protected] is for 12 plus pro model as per the invoice but the IMEI number which is written behind the phone is also same I.e for realme plus phone which I have recieved. How it can be possible having same IMEI number for different models. And the product was recieved by my family member on my behalf and when I came back and saw the product was wrong. So, I want to return this product as soon as possible.Kindly resolve this issue and return my payment back.Attached below are the photos for evidence.
