As a former Macy's employee, I can tell you that this goes against everything that Macy's associates are taught about customer service. I'm sorry that you were ignored. Even if the associates were busy, they could have and should have at least said hello and acknowledged your presence (and cosmetics and shoe associates are commissioned at Macy's, so by ignoring you they lost out on money).

One thing to do next time (or this time) is visit www.macys.com/tellus. This is a website that is at the bottom of all sales slips at Macy's, and associates are supposed to tell you about and encourage you to visit this website. Go there for complaints and compliments, and share your experience, with associate names if possible. Not only does that website go directly to Macy's corporate offices, the comments go directly to the upper management of the store the comments are about, so something can be done to address it. I love PlanetFeedback, but for Macy's, you'll get better results through their own feedback site. Again it's www.macys.com/tellus. I know my store managers actually contacted customers that left comments to follow up.
