Airtel — Unrequested jokes

My mobile used to receive funny jokes for the past 4-5 months. I have not requested it. Only last week, i came to know that you cut daily 1 RS for it. I dont even read those jokes. I contacted Manipal, Karnataka airtel office on last Friday that is 16-1-09, I asked them to remove it. But still i received the message on 17-1-09. When i contacted them, they said it will take 48 hours. But when the message continued even on Tuesday, then I went to your office and enquired. He said it was sent only on 19-1-09 and asked me to wait. Yesturday I received two messages -one funny joke and the other was from you stating that funny jokes service is cancelled and thanked me for my patience. Today, 22-1-09, I have received funny joke. Is this is your service. So I have decided to go to consumer court after lodging a complaint with TRAI regulatory board. This is not the service expected from a company like you
