Why do they never answer the phone

Cause there always busy, walking around doing nothing.

Because there always busy, doing nothing, something with the cashiers, no enough opens

What I do is try calling once, wait a little while, call back. If still no one picks up, I start selecting specific departments until I get someone on the line and then they transfer me to whatever department I need to speak to. The transfer is coming from an inside line so it works. Good luck.
