Quikr - wrong product delievered

Hello, i have purchased a refurbished mobile from www.quikr.com. The mobile is htc one m* **gb excellent condition(pic* invoice) order id ******** and suborder id:****** but i have received a **gb version of the fair condition model(pic*). The reason for mentioning excellent and fair condition is included in the third pic(pic*).
According to quikr excellent phone condition should have micro dents, micro scratches and micro paint peel but the phone i have received has a big visible Scratch on the back(pic*).
I feel like i have been cheated and mislead into buying a **gb priced mobile at the cost of **gb priced mobile. The price difference between the two is approx ****INR. I contacted quikr on the day of receiving the mobile March ** ****. They said they would contact me within ** working hours but nobody has contacted me. After ** working hours i called them and the said they are still processing my replacement request and i asked them to escalate to their supervisor Mr.Dadajhan. Mr.Dadajhan has patiently listened to my problem and said he would initiate a replacement but as i had seen many bad reviews on replacement policy i rejected that and asked them to compensate the remaining amount of ****INR which i felt i was forced to pay through their wrong listing which lead me to buy this mobile. Because of their bad replacement polices i requested them to reimburse only the exact amount ****INR i paid more. But they flatly denied saying "Its not possible". I also told them the reason why im not happy to send the item back because of the bad reviews where people have not received the refund or replacement even after *-* months.
Lastly today at April * *:** pm the quikr team contacted and said they couldn't help me in this matter. I feel cheated because of the callous way quikr is responding, I'm emotionally physically drained with the amount of time i invested on this. I want people to see this and be aware of how quikr can mislead them too. i just want quikr to notice this and hope it would provide me a solution. And also take up their Quality check seriously and wouldn't be careless to list misleading information causing significant financial loss and emotional disturbance.
I'm attaching all the evidence in the form of zip file. Please go through them. Thank You
