I have a prepaid Airtel number([protected]).I have requested to change my connection to post paid 1 month back.They have collected the documents, done the address verification.I checked after a week to why they are not activating the number i got to know from my dealer that there is some technical issue from Airtel side to activate the number .3 days back my prepaid number also stopped working .Now i am fully out of network.Airtel customer service is crap they don't have any proper update and giving wrong information.Finally i called the my dealer and he told that he cannot do any thing and i have to resubmit all the documents.Please help
