Hi Team,

I have ordered Realm 7 and Order Id : OD[protected]
But its not upto the mark as per specifications given and not satisfied with mobile. Main issue is camera mentioned 64 MP but its not upto the mark.
Picture quality is not good and same i have raised same complaint to Flipkart.
Flipkart team raised multiple return requests and tech visit but its rejected and replaced the my mobile. But still not happy with replaced product and raised refund request. Its raised 3 times and rejected. Now Flipkart team saying i need to go service center to resolve my issues and refund will not possible. I have connected multiple times to Flipkart and they haven't informed about this.

I need to refund my amount, Please help to resolve my issue.
