nicely ask the perpetrator to give me a call in 15 on my personal/private line at 555-1212(or some other random number)
I hope "random" doesn't mean "made up off the top of my head". There's a real human at the end of that random number, and they don't want the call any more than you do. Probably less-- especially the repeat that comes 30 seconds later. And you don't want the follow-up call asking you to give the number again because they must have written it down wrong.
Come to think of it, if the recruiting has been outsourced, you could probably give them a number that literally begins in 555- and they wouldn't bat an eye.
