Idea Cellular Ltd. — My balance getting deducted for unknown reason.

Delhi

I have been using Idea sim for the past 2, 3 years. Last week i got a message from 54300. " YOUR MISSED CALL ALERTS has been activated. Amount charged is Rs 2.0/- for 2 days. Renewal charge is Rs [protected]@1 Month as applicable. To deactivate sms UNSUB omcim to 54300" i had no idea where that message came from. And i have never activated such alerts. And i unsubscribed from that. But 2 days back i get the same message for the second time. i was so angry as i was not even aware of that. And right now just 2 hours back i received another 2 more message from 54300 and 58595. saying that "Thank you. We have received your request for CBC_Jokes_Pack and it's being processed. and the other one saying ERROR SUBSCRIPTION ALREADY EXISTS SSM P". Yesterday evening i had Rs. 14 in my main, And today it's all gone. No idea where it is.
What the hell is this.? Is this how you treat your valuable customers. I'm not demanding back my money i just want Idea to stop these kind of stupid messages and all that.
