If you relied on the advice of someone when making a financial decision or signing a contract, and suffered damages because the advice was factually incorrect, and the person providing it knew or should have known that, you might have a civil case against them for damages.
If this person was employed to sell loans, and lied about the loan terms, and you can prove it, that's not allowed. If the person was a fiduciary financial advisor bound to act in your best interest and chose not to, that's not allowed either. If this person is providing some kind of regulated advice and doesn't have or follow the restrictions of a required license, that also isn't allowed; maybe they are practicing law without actually being a lawyer.
If they're a non-fiduciary third party who just gives advice of a kind that is not regulated, and the advice was wrong, you might need to talk to a lawyer to try and figure out whether any generic responsibility they might have had to be right was violated.
Also, you can always total up your damages and ask if they will pay them, given that you relied on their advice, and it was wrong, and that's why the damages were incurred.
