Well, I called them today. They said it is beyond the usual time, the records didn't show it being mailed, and asked me to confirm my address, phone number, etc. The woman said that she would follow up on it, and if I hadn't received it by May 4, to call them again. Wouldn't you know it, the card shows up in the mail today. All's well that ends well, right? Thanks to everyone who took the time to respond to my question.
