Apple Watch Activation issue

I am beyond frustrated with the process of connecting my new apple watch to xfinity mobile.  I go through the pairing process and when adding cellular service get a message from xfinity saying "Uh-oh! something went wrong. We ran into a problem during the activation process and your information was not saved.  Please restart activation.  If this problem persists, contact customer support"

Well I've tried multiple times and the problem persists.  I called customer support last night and we tried un pairing, erasing, and re pairing my watch.  This did not work.  At this point the call was lost and I had to start again.  The new support person could not pickup where we left off.  so again we tried re pairing again it did not work.  at this point I had been on for almost two hour and the rep decided it was apples problem.  I was transferred to apple, apple explained my phone was paired correctly and if the cellular service was not working it was an Xfinity issue.  In fact they person mentioned that it isn't the first time they have dealt with this issue with an Xfinity user.  It was 10 pm so I decided to go to bed and try again in the morning.

Today we went through the same process for an hour with Xfinity.  The reps while very nice had no idea what they are doing and suggested they needed to send me a sim card for my Apple Watch to fix the issue.  Apple Watches have an e-sim and no slot for a physical sim card.  I explained this multiple times and was put on hold.  I was then mysteriously transferred to Apple again without my knowledge, nor the consent of the apple agent as the Xfinity rep explained the issue to Apple while i was on hold and was told by apple it is not an apple issue.  I was then transferred without any explanation from the rep.

I just need my apple watch to be added to my account.
