Airtel — fraudulent activation of services

Address:

Kolkata, West Bengal, 700025

On Monday, 14/08/17, an unsolicited service was activated on my cell.
I received a text message from AK-AIRSEP which read:

"NDTV Latest News service has been activated @ Rs15.0 for 13day(s). Txn ID S45007244, 14Aug17 12.53. ..."

This is the second time an incident such as this has happened to me; the first time I let it slip. Even though the amount charged was only Rs15, this activity must be stopped. I would appreciate the money charged to be refunded.
