I get these calls too😡.
They play 20 questions with my availability & when I try & pin them down to a time, they say, "oh I don't know when I can get away today. I just wanted to know if you were working/around/available."
My ever simmering temper tends to snap (sigh) & that's when I politely (sometimes) tell them that's fine, but I very well may be busy &/or scheduled if/when they call back. Sometimes they bite, sometimes they don't, but I refuse to play that game these men.
