Hello, Cristobal, I'm sorry to hear that you had a negative experience after the Home Depot store didn't notify you that the order was ready for pickup. Regarding the size of the skylight, the FCM 4646 skylight fits a 49-1/2" x 49-1/2" outside curb with a 46-1/2" x 46-1/2" inside curb. I hope you will give us a call so we can go over the dimensions of the skylight needed for your application because I confirmed with our warehouse that the product returned to us matched the product ordered. The phone number for VELUX Customer Service is 800-888-3589. Thank you.
