NEW PHONE ORDER STILL NOT SHIPPED

Hello, I placed a new mobile order 05/11. One of the reasons for deciding to go with Xfinity Mobile was because of the 2 day shipping offer. Before submitting my order and paying, it said place your order by 2pm and your phones will ship out same day. I needed to cancel my current phones by Tuesday to avoid a new billing cycle. My phones still say not shipped and I can not get any info from the virtual chats or live agents on the phone. I also need to plan ahead to take an entire day off to sign for them, and I am really disappointed in the communication and broken promise of shipping out same day. Can anyone please assist me with this?
