Address: Airtel main office

So i mistakely recharge with 181pack which give 1gb per day for 28 days but not know about that it not give unlimited call, so for that i again recharge with 151 plan which give 1gb and unlimited call for 24 days so technically I have 1gb+1gb =2gb of net for 24day and unlimited call for 24 day, so 1 st day i got 2gb of net but next day it give only 1gb of net and i check right now they again give only 1gb of net but show 181 pack is active
