[Resolved]  Airtel Prepaid — Unnecessary charges for receiving sms

I am Yogesh using airtel prepaid for more than five years. For past few months, I am receiving SMS from unknown numbers(56060,54321,etc) to download pictures,wallpapers,etc. Even though I ignore these type of messages I have been charged without downloading it. Eventhough I disabled service messages to avoid automatic connection of gprs.They send text messages like 'Dear subscriber click below link... to download rubbish things, I have just read it, after sometime I have received SMS ' Thanks for downloading the contents and you have been charged Rs.10,etc'. I have complained in airtel customer care, But they told that 'you have opened the given link so you are charged'. But I din't open any link and they are not refunding any amount for it. Sometimes without subscribing to any daily SMS, they are sending joke SMS daily and they are charging Re.1/sms. For many complaints they are not answering properly. I feel vry bad on it. I am going to disconnect from airtel.Necessary action should be taken to stop this.
