Airtel — deactivated sim due to non usage

Dear airtel,

I am airtel customer from last 7 years. I have moved outside india 2 years ago and airtel sim was working fine when i connect it to network for incoming messages. And i also use it when i visit india, most 2 times in year. But suddenly it gets stopped (De activated) due to non usage.

Now, without informing me (Due to changed policy) sim is disconnected. And to activate it again i have to visit home circle branch, which is mumbai in my case. This i believe unfair.

I paid money to buy this sim. If you wanted to de activated this sim, you should have informed me via mail. Moreover, you should allow me to activate online if i am ready to recharge it or pay money. This is unfair and unjust.

Regards
Customer
