Sir,
My no. is [protected]
I had not used Airtel STK service but, on following date the deduction of rs 30 are made, from the same number. When i made complaint to the customer care from last 10 days the executive say that "system down, system not show any deduction on your number, you have not subscribed for any services, your problem will be solved in short period, please call after sometime because of server problem"...
