While we did find quite a few customer reviews that said their credit scores improved reliably over time using the Credit Repair service, it's hard to recommend a business that has an "F" grade at the BBB because they didn't take the time to prove that their advertised claims were legitimate. If those facts are accurate, it should be a simple process to report them and clear up the concern at the BBB. If that happens in the future, Credit Repair will probably move up in the rankings among the services we reviewed; until then, we suggest you look at some of the higher-rated companies for your credit history improvement plan.
Credit scoring models usually take into account how much you owe compared to how much credit you have available, called your credit utilization rate or your balance-to-limit ratio. Basically it's the sum of all of your revolving debt (such as your credit card balances) divided by the total credit that is available to you (or the total of all your credit limits).
