Airtel — airtel my secure device claim issue

Address:

Visakhapatnam, Andhra Pradesh

Hi,
This is t s s p k l murthy. This is with reference to device request no. 2445520. I have claimed my device as i have subscribed to airtel secure plan. My device was dropped from my pant pocket and display was damaged. Now airtel was telling that, it won't comes under accidental damage but it will be under negligence act. So your device cannot be claimed.
I have not find any point in airtel terms and conditions about negligence act. I have asked airtel to mark it and send where the point of negligence is mentioned in its terms and conditions. Also how can they say it is point of negligence but not accidental. I have asked them written confirmation regarding above points. But airtel is not giving. Their customer care executives are failed to explain what is accidental damage. Then what the he'll they are selling these plans to customers. I need every thing in written, to proceed in the court of law.
