I am having a super card OF RS 599. Several times I sent msg by dialing *706# and they said (The message has been sent sucessfully by SMS) after this I did not recieve message. When I call help line they said we will resolve your problem as soon as possible but their is no response from them then today I call again help line and discuss my problem with them again and they said call on [protected] and they said you have send unlimited messages so thats why your SMS are get blocked so make a complain. I told them that I did not send unlimited messages even I have thousands of SMS mins in my mobile because I donot send messages except sending SMS to check my mins, validity date of super card.
