Apparently David's Bridal was emailing her for over a week to let her know that the dress had arrived early. They called and left a very nice (and confused) voicemail to let her know the dress was in and to make sure she was still picking up or else they would take it back.
Well she finally got it last night, laughed with the clerks about the mix up, and thanked them for their patience. And yes, she did update her file for when she needs to pick up after alterations.
