"In MY experience (of course you decide for yourself), the company is great and responsive for erroneous things that really should come off and that can be taken care of in the first month with the first set of challenges. I made the mistake of letting them convince me to keep on allowing them to challenge and re-challenge the same issues, with no progress made and considerable expenditure on my part. Be aware of the other ramifications of having these "challenges" on your record that they don’t tell you about. Good luck!"
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.
