Greeting guys.

I have got a quick question. I have been receiving calls from private number for the past 4 months plus, The catch is the caller does say a word, Sometimes I can hear background songs, sometimes I can hear the caller breathing, and sometimes sound like fan is running in the background. In one day I will receive about 20 plus calls and also these calls last about 10sec each. I also receive this calls at midnight sometimes at around 3 or 4 in the morning.
I approached my cousin brother who is an inspector about this, according to him if there is no verbal threat from that call I cant make any type of report, and even I make a report only the officers will find out the number and deal with the person. I even tried scolding, shouting even cursed at the caller but still receiving the call. If I choose not to answer the call frequency is higher.
Im using maxis by the way and im using this number since 1998.
So here I am hoping someone will shed some light on this issue. Is there any chances that I can find out the number or identify the caller, is there any chances I can trace this number.
Please advice.

by any chance I can obtain the number, I need to teach some lesson to the owner of the number.

once I manage to the number im very sure I will do this.

But I really need the number so that I can get "in touch" with my secret admirer.

That's the final step. At the moment I really looking for the number.

I hope some who has the internal links pm me abt this.. Really need the number.

Same here. That's the prob. But it seems like there is some apps that can do it. Also there is a setting in our phone where we can limit to receive only calls from the numbers that exists in our phone book. But its a hassle, I receive a lot of call from my suppliers and customers..
