I am a scheduler for KSS. You did the right thing by contacting the scheduler, and hopefully that scheduler got back to you as quickly as possible. Don't fret. Mistakes happen. Even shoppers with the highest ratings and years of experience make mistakes. MSCs make mistakes. All you have to do is make sure you learn from it, and continue on. Good luck!
I assumed that by calling through their recorded line, with their codes and verification codes it would block my number iike it does for the apartment shops. Nope, it didn't so the caller ID came through with my name and phone number.
