Airtel — airtel secure fraudulent rejection

Address:	Hyderabad, Andhra Pradesh
Website:	www.airtel.in/airtel-secure

I have claimed airtel secure insurance claim for my damaged handset and submitted all documents to airtel on 15 nov 2018.
My case is being rejected on the reason that IMEI is activated before the purchase around June 23 2017, where as my invoce is of 2nd sept 2017. So i have enquried this with samsung as i have purchased the mobile from Samsung.com only. The service centre has provided me the screenshot about the activation of my IMEI on 4th Sept 2017, which is after the purchase.
Airtel does not even submit me the document proof for june activation. so this is clear fraud rejection just to avoid the claim.
