Xbox and Amazon gift card promo failing...

Ordered back November was told I received by Christmas. Talked to 66 different representatives and two executive agents. Finally, the solution that we came up with is afirm.. is the finance credit company partnered with Verizon that offers financing on the Xbox. So they'll credit your account and then you just buy it from afirm. Hopefully after 77 days mine will be resolved in 24 hours. Fingers crossed. I also received my promotion for the Amazon gift card. However, it doesn't want to show up on the mobile app. You have to go to the desktop site. I hope that helps
