MISSING CREDITS FOR COLLISIONLINK CLAIMS

Has anyone in GM experienced missing credits from GM on Collisionlink claims?
I downloaded my monthly reports off Collisionlink and it seems I am missing 1 credit per month on average starting back in May.
Has anyone experienced this? How or who do you call for missing credits from these reports?
