My husband has 1 item listed in Chex, and it is reporting an incorrect amount. It is also incorrect on my CR. Which should I dispute first, or does it matter?

Thanks!

yes it matters, always dispute with chexsystems first. This is important because generally if you dispute with the bank first and they verify it as valid, it makes it extremely difficult to catch chexsystems in error with the time frame. Remember they have 30 days to verify. If they can not do that in the time frame given then they must remove you.
