[Resolved]  Tata DoCoMo / Prepaid — closure of prepaid connection

sir,
I am a govt. officer in central excise & customs and i took a new prepaid mobile connection of tata docomo and submitted the proof of identity and address. for proof of address i submitted the letter from a gazetted officer in the tata docomo outlet on 17/09/2009. now on 15/10/2009 they closed the connection without giving the intimation of closure of connection.
on talking to customer care they do not give a clear reply.
as they are not paying heed in this account i submit the complaint in this regard
