[Resolved]  Rediff Bol Messenger — dating scam on net

this happened on rediff bol messenger.
the name of the person was aniket.
he met on chat and told me that they provide dating services in india.
they told me to pay 1200 for registeration.
After registering they said they will send me a file with many profiles.
i was told to deposit the money in icici acnt no
in the name of MS Shera.
after i deposited the amount they said i need to pay 5000 more to get the file.
when i said i was given wrong info they said ok then deposit 1500 for 2 months of service.
i did that and now they even sent me a file but it was password protected.
again i called them and now they demanded more money.
total fake this buggers are cheating people big time.
i would like to know how i can launch a complaint so that in future more innocent people dont get stuck in this.
