Airtel — regarding validity recharge

Address:

769002

I am using my airtel sim bearing number [protected] from near about 10 years. I used to recharge 99 every month for 12 months to make it a lifetime prepaid sim card. I have spend near about 1200 rupees. But few days back i got a call regarding validity of my sim. They said i have to recharge rupees 35 to increase validity. Now my query is if they have to implement the validity recharge again then why then started rs 99 monthly lifetime pack before. Why i should always suffer. If the company cant generate average revenue then are we customer liable for that. We have done everything to keep the sim validity going. Now again if same thing we have to do recharge rupees 35 to increase the validity then the company should return my 1200 rupees so that i will recharge rupees 35 and increase validity every month. Company changes rule according to their need which is really a sad thing. We customer always have to suffer from such negligence of the company.
