How do I get a hold of the site manager at Walmart to speak to him or her to disgust my problems with them?

Call 221-2800 and ask for the on-duty manager.

Hopefully it wasn't a disgusting problem that tou wished to discuss with them.

Go right up to customer service desk when it happens and speak to manager in duty also.

If I were you I'd call and find the name and hours that person works
