Airtel — new 4g sim not activated after 16 hours also-[protected]

Address:

Patna, Bihar, 800002

I have upgraded my sim from 2g to 4g yesterday evening on 28 april, 2019 (Sunday). Until 10 am also my sim is not activated. I have called several times to customer care and also messaged on 121 for sim activation but in vain. Being such a reputable telecom service provider, i did not expected such a wasteful service. The urgency is that i am traveling today and i wanted to upgrade my sim so that, before 2 o'clock in the afternoon, my sim starts working. Please take it on priority. Looking forward to a quick action.
