Complaint Review: Laxmi palaypu

Hello, 
I have been scammed and defrauded by an individual and his company. The name of the individual is Laxmi Prasad Palapu, who is also once of the owner/partner/CFO of siriworld.com and IBSN inc.
He made me create IRA accounts and a LLC in my name and a bank account. the plan was to invest in Gold once i get the money to my LLC's bank account. After several process by IRA services i got my money transfered back to my LLC's bank account. His investment idea was to invest in Gold and hence i transfered the money to his company (siriworld.com) get the Gold delivered to me.
But he is unable to delivery Gold and hence i requested for refund. also, I lost more than $9000 dollars and its interest for nearly 20 months so far. I have been incurring bank charges for maintenance of bank account, LLC logistics and personal issues and what not. It has been more than 20 months now and i could not get refund from him. After several emails and requests he repaid only $4000. Now he is in no mood to refund rest of money. He is reachable only by email. He now owes me $5280 and never willing to refund. all his promises are just mere words. He gave several promises to refund my money but never seem to refund. He claims that he will be able to pay in instalments but never declares firm date and even if he does that he nevers follows it. This has been happening for nearly 2 years now. I have all the proofs related to my transaction and correspondence.
I am ready to go with FBI and/or followed by a suit. 

Here are his email ids.

*******NOTE*********
We have given enough time and the party has not repayed my money yet. 
Party which owes money to me requesting one week time to repay my $5280 and agreeing to repay by 24-Mar-2014. Hence resolving it in expectation. Update: As of 04/24/2014, the party does not repay my money.

*******UPDATE on 04/15/2014*******
The issue continues as of today (04/15/2014) and the party mentioned below does not seem to care of repaying the money which he owe me. Hence we have given one more week time till 04/20. We have also provided all the required options for discussion reconciliation as well. The party does not seem to care. 

Looking to start Legal ASAP.
