While this statement is posted on there website---------->"For all payments, the deadline is 90 days from the date of issue (or date of expected receipt) to report any discrepancies. We regret we are unable to investigate payment issues that are more than 90 days old."
I suggest you go to there website and click on Evaluators and a FAQ pops up. And read there statement in its entirety. There is a phone number on the site you might want to call. (800) 296-6699
