Just wondering if anyone knew how to cancel a return request or what Apple would do if I just don't mail it back. I purchased a refurbished MBA and the day I got it, it had power issues and audio output problems. After a Genius Bar and Store Sales technician phone call, we came up with returning the defective MBA and them sending me another of same value. A few days later I decided I didn't want it anymore and called for a cancellation but now I want to keep it. Do I just call to have the request cancelled or just not send it back?
