Trai — idea sim expired with any warning msg

Address:

BURNPUR MASJID ROAD Q.NO:-K-9/3, 713325

As discussed with idea support team they told me that since last 6 month you did'nt called outgoing so your number is expried and di not det same number...
But my concern is before my number is to be expired not a single warning message recived by idea.
And also they told me that if you want that number again so you have to move on postpaid... And chargen taken by me rs 95...
So, i request you to please look into matter and take some valuable step against idea.
