Xfinity Mobile - Can't purchase new phone because my internet is through Bulk/Managed Services

I have had Xfinity internet for over 13 years and Xfinity Mobile for around 6 years. Roughly 3 years ago, my apartment complex bundled our internet service as a non-optional extra charge to our rent using Xfinity Bulk or Managed Services. It was cheaper so it wasn't an issue and hasn't been an issue until this week when I tried to buy a new phone through Xfinity Mobile. The online purchase process was quick and easy, or so I thought. Yesterday, I get an email that they put the phone order on hold until I activated my internet. What? I already have internet and an Xfinity account that I can call about any time if I have issues or questions. This left me very confused so I tried to find contact info for Xfinity Mobile so I could call them. I was unable to find a phone number anywhere on the website so I tried the AI chat bot and even the bot wouldn't give me a phone number to call. That's rather inconvenient to say the least. I ended up digging around some online forums that actually gave me a number to Xfinity where I had to sit on hold to speak to someone who eventually gave me a number to call Xfinity Mobile, so I called them to inquire about the odd email I received.

Agent #1- I explain the situation and they said you need to activate your internet. I told them I had internet, they looked it up in their system and verified that I had active internet and said, I need to transfer you to this other department, so they did. Agent #2 answers and asks how they can help and apparently the first agent just blind transferred me and I had to tell the second agent the same thing I told the first agent. Second agent in the internet department looks up the account, verifies what I am telling them and says "I don't know why they transferred you to me, I can't help", and then proceeds to blind transfer me to Agent #3 where the whole process repeats. At this point I am pretty steamed because I have already been transferred 3 times and none of the agents had the forethought to loop the next person in. Agent 3 then proceeds to tell me to go to an Xfinity store, so I asked him what a store would be able to do that he couldn't do? His response was that I would be there in person and that would help. Wait what? I then asked to speak to a supervisor.  Agent #4 (supervisor) answers the phone and asks how he can help. By this time I am FUMING because I have already been transferred to 3 other people and nobody seems to know why I was transferred to them and nobody seems to know how to help me. I let this "supervisor" know how disgruntled I am because at this point I have been on the phone with 4 different people, had to repeat my issue 4 different times and nobody seemed interested in figuring out what the heck is going on!! I ended up hanging up on them because I am so mad at this point I cannot see straight.  I just wasted  an hour and 15 minutes with Xfinity because I got no results as nobody knew what to do, nor took the initiative to find out!

Here I am at this point wondering who the heck I need to call to fix this so I can get a new phone! Someone please help me before I cancel my service and go to another carrier as this hassle is not worth my time!!
