Airtel — airtel dth account balance expires 10 days earlier without activating anything by me for third time consecutively

Address:

Deepu para tarbahaar, bilaspur (CG), Bilaspur, Chhattisgarh

I m highly annoyed by the dth service of airtel dth service, my account balance expires 10 days before than the due date, i recharged my airtel dth with the monthly pack of 360 rs. For one month but the account balance expires in 20 days as the company deliberately activates some un necessary activation without giving me any information, i never asked them to activate anything other than my package, for which i pay 360rs. For 1 month, but it's now continued in succession for third time, a fraud is going on here with the airtel dth customers, & company's staffs refuses to do anything, plz help me for this
