Airtel — sim card registration failed - no service

Address:	400080
Website:	www.airtel.in

November 19-2018 - "no service" showing up on phone
November 20-2018 - spoke with airtel customer service and followed troubleshooting steps provided by them. Finally i was told to replace the sim.
Replaced sim at around 1:30pm.

From november 20-2018 till now even new sim is showing "no service"

Have called customer service about 4 -5 times after sim change and have followed all troubleshooting steps they have asked me to perform.

It seems airtel is not keen on providing quality. For 4 days and not sure how many more days my phone will be out of service. Will airtel deduct these days from billing??? Also are you willing to pay for the inconvenience caused for so many days of no phone???
