Airtel Customer Care

It is not worth saying that Airtel customer care (ACC) has still room to improve, rather they have a big warehouse to improve. Exactly, a lot more is desired from their pathetic customer care. For the same issue, every time I heard a different story.

Wanted to change my tariff plan to corporate scheme

ACC Executive 1 says:
Need your corporate employee ID copy
Latest Pay slip
Introduction letter from HR

ACC executive 2 says:
Need your corporate employee ID copy
Latest Pay slip
Introduction letter from HR
Clear all your outstanding dues and unbilled amount through Airtel Relationship Centers (ARC)

ACC executive 3 says:
Nothing required. Corporate employee ID copy is sufficient but send a mail from your official mail ID.
