This weekend I went to my local Verizon Wireless store and purchased a Samsung Galaxy SIII.
When I got home, I charged the phone and started using it. I was really enjoying the new phone and its capabilities and ease of use. Then to my disgust I found a bunch of photos and contacts on there that were not mine.
Here is a sampling.

Other contacts included mostly women, plus "Babe Girl" and "Sweet Women" among others. I just love how the last contact is "Wife."
Anyway, on Monday I went back to the store to demand an explanation.
The sales associate said that he had no idea that he had sold me a used phone -- that the phone had been brought in by another manager -- and he would exchange it for a new one but that I would have to come back in the morning so that they could void the restocking fee. I stood there at the counter to make sure that the phone was completely wiped and reset because I don't want MY contacts out there the next time Verizon tries to sell this phone to someone else. To make a long story short I really did have to go back to the store the next day and waste another hour waiting for the Verizon store to take care of this. I asked for a full refund.
I was in the market for a new phone and looking to change from AT&T but was so disgusted by this experience that I won't be back. Absolutely revolting.
