Mine didn't enter the tracking system until the day after I had received it. I had called because I'd been waiting a week, and the lady said to wait another week because it wasn't in her computer, and the next day, the replacement was sitting on my doorstep. The next day, I called again, to confirm it had been received. The first thing the guy told me after I gave my tracking # was that they had received it, but hadn't yet examined it.
