Idea Cellular Ltd. — False information by customer care

Sir,
I am Prepaid custumer of "IDEA Cellular Ltd" from more than last one year. My IDEA Mobile No is [protected]. I had been receiving the promotional calls from "IDEA". I called customer car ne 4444 to stop the promotional calls.
First I had been told that you sent the message "START DNT" to 55406 and it will charge Rs 3 per message. When I sent the above message I received the reply from 55406 that It is invalid command. Than I back to IDEA customer care. After the custumer people said sorry to me and gave me another number that is 1909 and Type "START DNT" and send to 1909. Also I had been told that the promotional calls will stop within 48 hours.
But afterwards their no response from 1909 and the propmotional calls continued. Si revert back to IDEA custumer care. Than again they said sorry to me and said we gave a wrong information to you and the message for stopping promotional calls is type "STOP DNT" and send it to 1909, your promotional calls will stop within 45 days.
I had been using the value added services like "Missed called alert, Jokes and dialer tones", which I requested to stop.
I had received the oral reply from IDEA custumer care that your "Missed call alert and Jokes" service is stopped immidiately and it will not continue further.
But still I am receiving the jokes and missed called alerts are still continued. I called IDEA custumer care many times, but I am not getting satisfied answer from them. I am losing my money in this value added services, which has been activated by IDEA withhout any request from myside.
