Xfinity Mobile Transfer Nightmare

Last Friday, I accepted an online offer from Xfinity for a five-year flat-rate Internet plan with free modem rental for the entire term and one mobile line free for the first year. Everything went smoothly until the phone number transfer. My number was successfully ported out of Visible (I even received the confirmation email), but Xfinity has been unable to activate it.

Since then, it's been a nightmare. Multiple chat agents gave me ETAs, opened a “high-priority” ticket, and assured me it would be fixed — but there has been zero progress and no updates at all. On Saturday, I even went to a local store; they couldn’t fix it either and just told me to wait.

I’m leaving for a road trip on Tuesday and really need my phone to work. I’ve transferred carriers twice in the past five years with no issues, so I truly didn’t expect something like this. Is there anyone who can actually help resolve this? An ETA of days is definitely unacceptable. TIA.
