I just called 3 "AT&T company" stores in Miami Fl. and each gave me a different answer. One said they are getting replacement phones next week. I was clear that I had a current Note 7 and needed to do an exchange, not a new purchase. He said next week, no specific day. One store said they had no idea and the other said to check the AT&T website that it is constantly updated with Note 7 info.
This is what is so frustrating. Everyone has a answer, but they are all different. For me, this is where Samsung has dropped the ball. Ill still stay with them because I don't like the iphone, but the lack of direct info from Samsung is not good.
