Did the calls stop after you answered? It would be worth it to not be awakened 30 minutes before my alarm goes off every single morning because of these calls.
These people have been ever-so-conveniently calling me every single day, 30 minutes before my alarm goes off to wake up for the day (how did they know that was a pet peeve of mine? Bravo!). After searching the web and finding that the number belongs to allaboutthebaby.com, I e-mailed their customer service and asked to be removed. They responded and said that they were removing me from the list. Were they telling the truth? We shall see.
