why can't I hear the deli when I call and nobody will pick up when I call and dial 0?

Not sure all of their department are like that and they are not that busy.

Because it's walmart, nobody wants to actually work

I believe it depends on the day and the time you call; especially now since the Pandemic, they are short handed .

I am not sure why. I agree, try customer service

I can't answer that question. Call customer service
