Airtel — airtel secure service

Address:

Kolkata, West Bengal, 700053

I have been using airtel secure service since the very beginning. Recently the screen of my phone broke and needed a replacement, for which i asked airtel for help for my screen repair, but it was declined straight off. The reason given that till june of 2017 i was using a samsung note 5, the price of which was ₹ 60, 000, and i was paying the airtel secure amount accordingly. After june i started using an i-phone 7 the price of which was ₹ 50000.
I have been denied the services of airtel secure because i have been charged for paying for samsung and claimed insurance for apple... I was under the impression that my current phone is insured under secure because while charging for the same airtel was never interested in clarifying or knowing which handset are they securing they are just interested in monthly premiums which they get on time.
I don’t understand why don’t they repair my handset for which they have charging for months. This looks like a pure scam
