Credit bureaus must send a notice of any corrections made to your report. Sometimes, a deleted dispute can reappear on your credit reports if the lender proves its claim is valid. If you find a derogatory mark reinserted on your credit reports, you can dispute it again. If you believe a credit reporting agency or one of your creditors has violated the FCRA, you should submit a consumer complaint to the Federal Trade Commission (FTC).
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).
