New Xfinity Mobile activation with multiple issues - can't receive texts on my new phone or set up voicemail

I just switched from Verizon to Xfinity Mobile. I brought my phone number over and purchased a Samsung Galaxy S21 to use with the account. I started the activation process on Saturday 9/4 and have had multiple issues arise since. Here's where I'm at now:

- My number has been ported over and works on the new phone, Verizon has deactivated my account on their end

- Though I am using the new phone for calls, Xfinity still shows my device as inactive on their site

- I cannot receive text messages on the new phone but I can send them successfully

- I get an error when trying to set up voicemail

At this point, I have talked to 8 different Xfinity reps. Multiple attempts have been made to fully activate my phone and solve the text messaging issue but none have helped. Each time a rep helps me they ask me to wait 24-48 hours for a change to go into effect. Nothing changes, I call and start from scratch with someone new. It would be really great to have a dedicated customer service rep work with me to get this solved so I don't have to start over every time I call. Is that a thing or am I just dreaming with that?

In the meantime, I have been googling. I'm not the first person to have this issue and in fact, there's someone dealing with the same thing on the Xfinity forum right not. I'm sure someone at Xfinity is aware of how to solve this issue but experience has proven that not every rep can help with this. If anyone has any insight into how to get this phone working it would be much appreciated!
