Flipkart — No replacement or refund for used mobile that I got until now

Seller Name :
As per flipkart it is mentioned as "DealsParadize"

Description of the incident :
I ordered a mobile(Mi 11X) which costs about Rs.26, 999/- and the order was delivered on 12thNov, 2021. I've taken the order and paid the cash. When I opened the package the brand box given by the Mi was full of scratches but was okay when the seal was still present, so I've opened the box and the contents are all there. And when I switched on the mobile the usual setup which was supposed to do for a new mobile which is language setup, email login and security, there was nothing. It directly opened up and there were a lot of applications which is not given by the company like "live video chatting and dating apps, netflix, phonepe, hindi news channel app etc". So, I decided to request for a replacement and searched the flipkart options and did not find the reason "used product" in the replacement policy reasons and so I've kept it as screen damge which was present. The day when the technician visit was supposed to happen I got a message from flipkart, the details of him and when I have called he said, he was on leave so he won't be visiting. I called the flipkart customer care and said the same and they have rescheduled it for the next two days. And when it didn't happen, I called the flipkart customer care again, they said, " there seems to be a problem", so then they cancelled the replacement and again raised a new replacement on 18thNov, 2021, I said okay and the date given by them was 22ndNov, 2021 1:30pm the final issue resolve date. And from then I'm calling them repeatedly and saying to wait for 24hrs and then on 23th, 1:30PM the same thing that it will be on 24thNov, 2021 1:30pm. I'm facing difficulty to proceed the issue furthur.

Desirable resolution :
I prefer a refund as a 1st option because this is such a bad experience.
I prefer a replacement for a new one as 2nd option in case refund is not possible.
