was told there was a federal warrant on my son and they calling all his family i must of ask to many questions because she put me on hold and didn't com back

I was told my son had 3 warrants for a loan company.  Jp chase for $521.30 and they had drop $1000 of it off. I took the info and was supposed to send money only by money gram not western union but moneygram. He gave me the info which was company security code 9797 .... Company name bloomberg processing company. ..city/state....Atlanta /ga..... account number 2925490. I need the bill on black and white so I can see and make sure became can't just send money to whoever. First I called jp chase and then the decision can be made. The guy who gave me the info was supposedly Mathew McGregor. It made me very nervous and someone could get a heart attack just from getting this type of news.
