Airtel Prepaid
Rs. 10 gets deducted periodically

My cell phone no. is 9956144114 (UP East). I have the above mentioned problem and they are charging Rs.10 and they send the message "Thanks for using (Cricket Day Pass, Alert) subscription service on Airtel WAP. You've been charged Rs.10", though I've not.

I've already lost a lot, it keeps happening periodically
