For those of you that took advantage of AT&Ts Trade In Program when they purchased a new phone, have you received your promo card / credit or any kind of update? We traded in my wife's iPhone 4S when we got her an iPhone 6 and it was mailed to AT&T on 9/22. Tracking it from AT&T's end, it shows Device Not Received. I used the mailing label they provided, which unfortunately didn't include any kind of tracking as it was First Class Mail. I contacted AT&T a week ago and they weren't able to provide much info and suggested I check back in a few days. I just sent a follow up email this morning. Has anyone gotten any further than Device Not Received?
