prank calls or whateva waste calls!

some idiot guy messing with me!
he/she keeps calling me and when i pick up he disconnects.. it has been a long time after when this started..call comes after a week/month from the same number...
i try to call back on that number i need to put a 0 before it.(so basically its a number out of delhi)

is there anyway to get rid of such calls?

Some mobile phones have a blocking option for certain numbers, try checking in your phone. You can also call Airtel and ask them if they can block this number from your sim if it is possible.

I think the best thing to do would be to report this number to the police or I think there is a special number to call for nuisance calls. Best way to teach the caller a lesson as well.

thanks guys! in my phone there is not blacklist/rejection option for a contact so i downloaded a blocking software .. if the guy uses another number then i will follow ur suggestions mr.umang.
