Be VERY wary of recovery websites. Take a look at AsstMod's collection of them here:
https://www.forexpeacearmy.com/community/threads/recovery-room-scammers-who-spammed-the-fpa.64442/
Every one of those sites was designed to look helpful while really working for something else - stealing more money from people who had already been scammed.
financialfundrecovery.com - unless you personally visit those claimed offices in the US, how do you know it's a real office or a virtual office to thousands of companies. In some cases like this, the address is an empty lot.
You said "They reached out". How did they know to reach out to you. The FBI and CFTC wouldn't hand your private contacct details off to some recovery service. If they claim to be working with or for a government agency, ask that someone from that agency start an email exchange with you from an email address that ends with
.gov not gmail, yahoo, or something where anyone can set it up.
If they claim some hacker gave them your info, ask yourself what's more likely: That a "nice" hacker is handing out victims info to a highly questionable recovery service or that the service is really a recovery room scam working with or for the scammers to get more money and financial info out of you?
They may claim no fees needed up front. Then again, your fake broker never said anything about needing a fortune to improve your credit score to be able to send money to you. (BTW - Thanks for giving that detail - I was getting bored with the usual excuses scammers give and that one is new to me.)
Legitimate recovery services are few and far between (probably less than 1 in a thousand). Do you feel lucky enough to take the risk.
Instead, focus on reporting this. Before reporting, gather all the evidence, including ALL details of how and where you sent money.
If you sent money via bank wire, report to your bank and the receiving bank. If by some other transfer service, report it to that service.
If you are in the US, report this to the FBI (via IC3.gov), the FTC (via eConsumer.gov), the SEC, and your State Attorney General. Reporting to the State AG may sound odd, but one was very important in taking down am offshore Ponzi scheme recently.
If there are other countries involved, report to the financial and cybercrime authorities in each country.
If you were lured into connecting to this broker via an online "friend" or "date", report to Gaso.org.
