BSNL Mobile — Issue of more than one sim card of bSnl mobile no. [protected], account no.[protected]

Address:	Ghaziabad, Uttar Pradesh
Website:	BSNL

My mobile no. [protected] account no.[protected] postpaid connection was issued from ccn meerut, in mid of year 2013. From last three-four month my mobile bill is not proper. There were several call diversion during call to another no. Today, my friend got call from my mobile no. [protected] on his no. [protected], also got some message from my no. [protected]. But i did neither call him nor send him message.
My complain is to check that, whether bsnl office has issued more than one sim card of the same mobile no. If so please disconnect the other person mobile no. [protected] inherently. And also take panel action in this matter inherently.
If this problem is not short out inherently, please disconnect the no. [protected]. And issue me another no.
