I came in today to ask a simple question. I could have called customer service but chose to come in to the store to speak with someone face to face. What a waste of time! I had recently upgraded my phone at Costco and had FANTASTIC customer service (highly recommend upgrading your phone there!) The girl helping me rolled her eyes and told me never to upgrade my phone at a non-corporate store- I assume because this taps into corporate store's business. She also was unable to answer ANY of my questions. When I asked if I could speak to someone who was more knowledgeable she got extremely defensive and rude. The least she could have done was grab a manager to reassure me. But she refused. I've been an AT&T customer for 5 years and this girl made me question my choice. Wish I would have got her name but I was so frustrated with the entire experience that I walked out and immediately placed a call to customer service. Waste of time. For better customer service visit Costco, call customer service from the comfort of your home or visit the Tempe Marketplace location.
