AIRTEL PREPAID MOBILE
Promotion ads eating up my money

I am a prepaid customer of airtel with mob No 9915659045. I have been to airtel service centre umpteen times to get airtel to stop promotion/ dirty messages. I have been charged amounts for SERVICE MESSAGEs that I inadvertantly hapen to open; despite strict instructions to stop these they DO NOT STOP despite registering for the same. Today I opened some silly message & promptly got a message THANK YOU FOR... you have been charged Rs 99.

I want NO MESSAGES IN MY FOLDER, SERVICE OR PROMOTIONAL!!

Is it possible to comply or should I seek legal help.

What happens to hundreds of ruppees already gobbled!!!
