I think it depends somewhat on what the cursing at me really means - if the recruiter said something like:

"Screw you, you little shit, I can't believe I wasted my time with your worthless ass!" and hung up that would be one thing, if they said "oh damn it" and hung up that would be another, both still rude but quite different. I'm assuming of course it was probably something like the second but the phrasing makes it sound like the first.
