Airtel — sim block airtel cheats

Address:

110095

I received this text message from airtel “pack validity for my airtel no will expire on 30-nov-18 & outgoing services will stop. Recharge for continued services. Dial*121*51#”. Why i need to recharge minimum 35 for validity only and if i do not recharge then my incoming service will also stop after 15 days. I came to know that i have to recharge after 28 days for validity everytime. I will have to recharge time to time only for the validity, but when i purchased the airtel sim card that time airtel gave me life time validity. Now airtel is cheating to customers.
