AT&T at 331 Mamaroneck Ave, Mamaroneck, New York.

THIEVES AVOID LIKE THE PLAGUE! Like the other reviews say, these people are thieves and Scammers. There are numerous negative reviews for a reason. Even though it says it on the outside, be clear that this is an AT&T AUTHORIZED RETAILER. The average person does not know what this means. Essentially, it means that they are not associated with AT&T in any way other than the fact that they sell their phones. What does this mean? That they can makeup their own rules which at times go directly against corporate policy. This inherently would not be bad, but the conflict is that they still advertise the great policies of corporate AT&T throughout the store. BAIT AND SWITCH.
Long story short, a friend of mine overpaid 160 for a 30 dollar brand new phone. When she went to return it the next day, she was told that they do not take returns on full priced phones. When she pointed to several of the signs that indicated the 14 day return policy of AT&T, she was simply told that this doesn't apply. They were of no help. When I contacted the corporate office of AT&T, they were saddened to hear that a seller of their products would not take a return, as they had never heard of anything like that before. They also sadly informed me that because the place on Mamaroneck Avenue is an AUTHORIZED RETAILER, they can unfortunately make up their own rules as they go along and that there was nothing AT&T could officially do. Please do not fall for the same trap. Either make the trek to the AT&T store in New Rochelle or find a corporate location. I myself an a small business owner and realize the importance of customer satisfaction. Hopefully they either change their business practices or shut down before other people are taken advantage of. Extremely rude and impatient customer service.
