Airtel — dth/ i am complaining about the disconnection of my long term annual infinity hd pack before its expiry

Address:	Mumbai, Mumbai City, Maharashtra, 421301
Website:	www.airtel.in

I have subscribed the annual pack of infinity hd pack last sept 2018 and that supposed to expire on sept 2019, but before its expiry airtel dth has disconnect the pack and added some other lower cost pack in the name of 'pay per channel' which i dont want. I just want my pack return and let me use it until its expiry.
As per trai regulations and guideline the dth providers cannot disconnected or migrate the long term package subscriber users until the pack expire or until users request.
I kindly request your support to get my annual subscribed pack (Inifnity hd) back.
