AT&T won't give me the $650 iPhone trade in credit that they promised
Sometime in October 2016, I traded-in my fully paid iPhone 6S Plus to the AT&T Abbott Branch in Anchorage, AK after purchasing my iPhone 7 Plus under AT&T Next at Apple. I learned about the $650 trade-in promo so I went to the Abbott Branch and traded-in iPhone 6S Plus. I clearly stated to the AT&T personnel that I purchased my iPhone 7 Plus at Apple and it's under AT&T Next. She accepted my trade-in without issues. Fast forward after 7 months, I happened to check my billing statements and learned that I was never credited back after all. I went to the store and told them my problem. They were able to find my trade-in transaction, but was never able to resolve it, and they needed to call Customer Care for help. They said it caused some issue because I didn't purchase my iPhone 7 Plus at AT&T. After multiple calls to the store and customer care, and multiple visits at the store, they have decided to issue me a $272 credit instead. If they could have told me that I can't trade-in my iPhone 6S Plus without purchasing an iPhone 7 Plus at their store or online, I could have took my phone elsewhere. AT&T KEPT MY IPHONE 6S PLUS FOR 7 MONTHS FOR THEIR OWN GOOD! It's surprising that when I searched on your forums, other people are having the same issue as well. I am empty handed and I felt like I'm scammed. This is beyond unacceptable AT&T!
