Welp, my experience so far has not been to great with how the T-Mobile is handling this voluntary "recall". Went to a store to get a refund, told couldn't since I flat out paid for it and also got it from T-Mobile.com. Was provided a UPS shipping label and told to ship out phone and I "should" get a refund back. Person did not sound to sure. Called the 844 number and spoke with a rep saying that was the wrong procedure and that we should go back to the store.
Went to another store, told them what happened. They started the refund process with no issues until they found my phone "canceled". Guess when the first person tried to help me, they did it the old way the stores were first told to do and not the current way it is being handled. Unfortunately, could not get my refund in store and just got back from shipping the phone out.
I love my Note 7, really wished it wasn't plagued with the battery issue since mine worked. Only got hot when I was playing games, but still holdable. Did not overcharge it. Would have waited till the new Note 7s came out, but family was urging me to just return it since the media has been blasting it so much.
