Airtel
Activation of VAS without my consent

I have been using airtel since last 3 year i am always facing the problem of deduction in by prepaid balance

Even though I dont activate any of the Value Added Services how come they get activated.

I am having 3 Airtel no. and to the addition of all on my all 3 no. same picture mesg service got activated how is it possible the company is debiting the balance from customers a/c

Its seem Airtel just know to increase customers and not give after sales service
