How often do you guys get burned on big skip trace lists?

[Adam Silvers]

After having many successful smaller lists in the 500-1000 lead range, I have begun expanding my lists to 2000-4000 for my VAs and after doing so, I got burned badly. Skip traced the list using Batch and the list yielded an abysmal contact ratio of 1%, a correct number ratio of 10% and basically left me out $1000. This was just a simple high-equity absentee list from multiple cities that I have done many times with a healthy contact ratio of 15-20%. Do you guys just bite the bullet and move on when this happens? Do you demand refunds? Or do you have a system in place to help mitigate the possibility of getting burned on some of these skiptraces? I just feel like it will be much more intimidating to proceed to large lists in the 5000-10000 lead range if this is constantly a possibility.
