You cannot directly get full details about the number and its owner, as it is not allowed in our country.
You can rather make a call to customer care executive and tell your problem that why cannot you directly file a case on that number and owner. They may give you a better and useful suggestion, about what can be done for the respected purpose.
Though it has been mentioned by fellow members of ISC, that you can track the location of that number. And with that, you will have to think and estimate about who it can be. At least you can make a list of your doubtful friends to self investigate for a while.
Hey, here is an another solution. Just do not respond to any activity being done by that number, for a few days. And then try calling it from a P.C.O. booth or I will suggest you to call from your co-worker or neighbor's number (of which you are sure that your friends and other relatives are not having any contact), so that 'miss caller' do not get a doubt on you. You will have to change your tone and name while talking on phone, and also try to behave like you were trying to make a call to some other place, and wrongly it was connected with him. Forcefully remain at your point that 'NO, I had called to my uncle house at XYZ location. No no, it is the same number' etc etc.
By getting frustrated, the caller may tell his/her real location in anger, that you have made a call to this location and its not your XYZ. So, you can at least get his/her location.
Friend, try it for once. Then it all depends on your acting and tone, and his/her attitude and cleverness.
If still you are not able to get rid of it, then after waiting for next 15-20 days, you should message that 'miss caller' to either tell who is he/she or stop making calls to your number. and after that you should surely go for registering complain against that number.
Good luck Sujesh! I wish you will get rid of this problem.
