Flipkart (ekart)Jeeves - Insurance policy and it’s compliance

This is in reference to extended warranty coverage from Jeeves/Flipkart.

My mobile was shipped to Jeeves support centre on ** June **** in accordance with Jeeves process and required documents.
Policy assures repair/replacement of faulty parts and return within ** working days.
Accordingly, I had been repeatedly calling support centre for repair and return status of my mobile, however there has been no update all this while.

When I had sent my mobile, there was no issue other than colour split line on the screen. Mobile was in good working condition with absolutely no concern related to battery or performance.
After multiple calls to Jeeves support and follow-up emails, on *th July, almost after a month's time I am being told that my mobile phone battery is swollen and can't be repaired.

If Mobile had battery issue, why did it take so long for you to notify ? To me battery issue seems to be due to your negligence, mishandling or incorrect power treatment.
I request you do the needful and return my mobile in proper condition.
