Xfinity Mobile is running through deactived business account and not residential

As the title states, we used to have a business account and about a year ago we transferred to residential. About 3 months ago we did bring your own device and we added 3 phones to our residential xfinity mobile account and now when I try to buy a new phone I get the error "Contact our agents, who will help you make changes to your account, including new purchases. Give us a call at (888) 936-4968 to talk to an agent. We're available 24/7 to handle your needs.". Talked to multiple comcast reps from business, residential, xfinity mobile, and the security team, no luck.
