Nike has been a bit weird lately, I bought three pairs of shoes, and returned 2 (2 flyknit maxes and a flyknit racer, the maxes were returned and the racer was kept). I got a notification that the flyknit maxes had been refunded, as well as the racer. The full charge of the order went back onto my account. I called nike to notify them that I still had one pair of shoes, and that their system mistakenly refunded me for all three. The dude couldn't comprehend as to what was going on, and kept saying that all three were refunded to me. In the end, he just said keep them, and that was that.
