This provider offers a "performance-based refund policy": after you've been a client in good standing for 6 months, you can request a full evaluation of any progress they've made in repairing your credit. For every improvement or deletion they've made, eCreditAttorney will count it as a $95 value. If the total of monthly fees you've paid exceeds the value of $95 per improved/deleted item, you'll get a refund of the difference. Do the math, because that's not a fantastic deal: at $29/month, eCreditAttorney would only have to make two improvements or deletions over the course of 6 months to demonstrate adequate "performance".
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.
