Essentials: for a one-time fee of $69 and monthly fees of $69, you'll get the basics of a personal case advisor, personalized dispute options, and an online dispute manager for tracking everything you submit to the various bureaus, agencies, and so forth. You'll also get access to financial management tools to help you budget for savings and paying down your debts.
If you find information that is incorrect, you can file a dispute. Remember too, that items on your credit report that you don't recognize could also be potential signs of fraudulent activity — someone working to secure credit in your name for their own use. Make sure you're clear on items that could potentially be fraudulent, versus those that may simply be inaccurate.
