Avoid Heather at the Sprint Store located at 9494 W Northern Ave, Ste 111, Glendale, AZ 85305 - She doesn't listen to a word you say, and is extremely disrespectful to customers who are not experts with smart phones. She is condescending, and talks and talks without shutting her mouth long enough to listen and fully understand the true issue. She makes completely false statements with a tone of arrogance. Why? because she doesn't LISTEN or take the time to find out what's truly going on. This woman needs to close her lips and use her ears. Literally. After becoming exasperated, I told her calmly and repeatedly that I wanted to end the conversation and leave the store, and she kept badgering and provoking me into a near argument until I raised my voice. This must be a strategy of Sprint -- angering their customers -- because she was cool as a cucumber, then she had the audacity to say, "Stop yelling at me." Ha! Get a clue. I thought the foreign-speaking phone support was terrible. The Americans in person are worse! I'm sticking with T-Mobile.
