Airtel — airtel lifestyle service activated without any initiation from my side

Address:

Faridabad, Haryana, 121003

There was a life style service activated on my airtel number from last 3 weeks and i noticed it today(25/4/2018). without my initiation to start the service, it has started and costing me 35/- per week i.e about 105/ for 3 weeks and i'm at the loss of it.
cheap tricks by airtel to gain money.
worst service ever.
