I suddenly got the news from my company that you have to leave for USA. I called airtel indore customer care form Delhi airport that I want to put on hold my landline and mobile connection. They replied that you will have to fill some form and submit to our indore center. How can I fill form from Delhi and submit it to indore center. Instead I asked my friend to so so and he done that still I am getting telephone bill for both landline as well as Post paid mobile. Even they charged a large amount for the old bill and it was out of my expectation even impossible because I didn't even use that much. As I will go back to India, I am in mood to disconnect my airtel connections!
