Address:	0000
Website:	AIRTEL

I am your valued customer since long. I am residing in uae. Whenever i am reaching india.. I will recharge and use the number. I have no other connection. I have given my number to all my contacts.. Bank transactions etc.. If i am away more than 3 weeks, i used to make a call from uae, so as to activate my accounts.
I left kerala on dec 7th last year.. I forgot to activate before march 7th... Remembered on march 10th only. Then, they say... Your call cannot be connected... May i know the reason? Can i get back the connection? Please get it corrected.. I am reaching kerala next month. How can i use the number again?
Other network providers are providing solutions to get uninterrupted connection.. What i have to do, so that next time my connection will not be interrupted.
My cable connection also, is airtel.
I dont want to lose my number, or want get another connection. Please help me.
I am ready to pay for 1 year interrupted service
