Trai — by mistake sent an sms to 123

Sir,
I am arya binu from kerala, ernakulam. Yesterday by mistake i sent sms 147 to 123, from my mob no.[protected] actually i need voice 149. I was not used this sms package up to this time. I called the customer care for cancel the sms 147 package. They said no provision to cancel the same. I think actually this is a cheating by bsnl to their valued customers. Anybody can have this type of issues. Actually i am a valued cutomer for bsnl last 5 more year. They never do this type of cheating to me and others. They have no loss related to this issue. They can simply solve this issue, ispite of this they never take any action to solve the same. Kindly consider my problem and help me to solve the issue.
Yours faithfully
