Airtel — value added services started by company without consent of consumer

Address:

Varanasi, Uttar Pradesh, 221106

I am 65 year old pensioner and using airtel mobile number (I. E [protected]) from past 15 days but last 2 or 3 weeks company imposing value added services at me without taking my consent and regularly deducting my account balance. It is not the first time that the company did this to me it's been done by the company regular basis. It's my request to kindly look into this matter and get me refund my amount which was deducted from my account.
Also make sure this practice may not perform in future again.
Thank you
