This is literally the worst Walmart in Mesa when it comes to customer service. I came in to fill a script for my son. Of course it's urgent otherwise I wouldn't have waited last min to fill it. I was told that it would take 45 minutes to fill, so I decided to wait. Forty five minutes later I was told that one of his scripts wasn't covered by his insurance. He has two. According to the rude pharmacist neither one will cover it. Well being as that she didn't know what other type of insurance he had I'm failing to understand how she knew this. On top of the rudeness the scripts that were covered still weren't filled.
