Vodafone — Company has Call Details but Doesnot Share and thus don' t Help in Searching of Lost Mobile Phone

Hi,
The Company Gives the itemised bill showing that it have the Call Information.
My Mobile was Stolen and was Continuously used. The Service Provider couldnot Provide the Last Call Details on Customer Care. If that was Available the Phone could have been Traced and would have got the Stolen Phone back.
Company has Call Details but Doesnot Share and thus don' t Help in Searching of Lost Mobile Phone.
