How do you guys deal with your annoying ISO reps?

Ive got reps email blasting, bomb texting, and blowing up my phone constantly for stupidity.

Ex. Merchants is 63% levered, rep claims merchant has 100k offer (which would lever him 72%) needs 120k to compete. I tell him its a nice file ill get 25k max which is a stretch. The rep begins to rip into my underwriting and how incompetent our company is. Obviously my feeling are not hurt my faceless ISO's who are trying to make a buck, but come on if ur file is garbage then ur file is garbage. End of story.

Just curious on others approach in this area.
