Airtel Prepaid
Wrong deduction of amount

I am Pravakar Adak. from kolkata. i am a prepaid customer from last 4 years. my no is :9933855902.

on day of 30th July I have got a massage that "Thank you for subscribing to airtel friendz chat. you have been charged rs. 10/- for 10 days. but here I donot activate any friendz caht services. This time my a/c balance was very low :(Rs.0.19).after this service activating my a/c balance: Rs. (-)9.79

here my quiestion is where i donot activate any friendz chat service or any other, so why i give its, charges.

I also complain to airtel same day. my complain no is :30731676507 by Mr. Ujjal Sadhuka on dated :30-07-09). Mr. sadhukha says that you will be know against this deduction by sms on or before 04th August. but today 5th august. I donot received any sms or call from customer service..

So in my sight Airtel provide very bad service. They deduct amount from customer without any resion.
