Flipkart — Open box delivery product not found right

Dated 8 Aug 2022
I had ordered a realme pad x 6gb 128gb varient, but got a 4gb 64gb varient. As the delivery boy did open box inspection in front o[censored]s we were only able to see that the tablet, the charger and the cable I.e. the content of the box were there but after he went away we also saw that in the back of the box its written 4gb 64gb variant instead of 6gb 128gb which was written in the invoice that we paid for. But now they are refusing the return/replacement of the said product
