Thanks for choosing 6t seconds wap on your airtel mobile. You have been charged rs49.0 for 15days. A/c balance: rs23.62 at 00:04. To deactivate, call or sms stop to 155223.
Airtel deducted this amount from my account and activated some unnecessary pack without my consent. I really don't understand what is their problem. This is most frequently happenin with most of the people. And the costumer service executives of airtel also do not agree to forward the call to manager nor they agree for refund. So some strict action should be taken against this cheating frauds. Please give me justice.
