Telephone etiquette, put down phone in my ear

I called in and lady clearly didn't want to assist, for example she said I'll check stock and then 2 seconds later say what did you say I must do.

Then when I asked her to check how much stock she has, she put down the phone. When I called back the lady didn't even bother to apologise on her colleagues behalf or even say I'll go ask her what u asked for.
