Flipkart — Refund not approved.

Kalna, burdwan, wb 713422

I ordered a mobile. For a software issue i wanted replacement. 1st replacement cancelled. Actually technician visit scheduled. But without visiting technician reported that my device had no issue. 2nd time replacement approved. Got replacement clarifying the issue to the technician. But issue is the same. Now i want refund. But they are not approving my issue. Please do the needful as i can get refund. I have already ordered it's back cover and tempered glass and already delivered. Now what can i do with cover and glass without mobile.
