I'm not sure whether Brookwood Loans is licensed in CA. I checked the license database of California Dept of Corporations "http://www.corp.ca.gov/FSD/licensees/default.asp" and did not find their name, although as per their website, they are available in CA.
Making minimum payments will never reduce your debt because the high interest rate on the loan will will increase your debts. Is it an installment loan? If it is so, then what are the monthly payments under the agreement?
