Never got the ATT $650 credits towards iPhone 6 trade-in for new iPhone7
Hi, under the $650 credits promotion last year, I have paid off my iPhone 6 and traded it in for an iPhone 7. It's been more than a year and the $650 credit never kicked in. I'm still paying for the iPhone 7. I tried opening multiple cases with the customer support but never heard back from anyone. Every time I call, I get the same response that the case has been approved and I would get the credits from next billing cycle. But that has never happened.
In a nutshell, I completely paid off $750 for iPhone 6, returned the device to ATT and started paying for iPhone 7 again under ATT Next contract. Can someone please look into this issue and resolve this?
