I just got off the phone with Comenity, and they said to expect the re-issued card (the one of higher quality Vx sent an e-mail about last week) in 7-10 business days (i.e., they should be starting to show up at the end of next week).
The printing in the "windows" of my silver card is starting to rub off, and you can feel the embossed CCV code on the front of the card. Pretty shoddy construction.
