Xfinity support keeps saying I will get my SIM unlock email but I never do

It's been a few days and Xfinity support is giving me the runaround. They have now shut off my mobile service since I requested my number to be ported over, and I'm completely stranded with no way to even call support. My new service doesn't work because my phone is carrier locked. Live chat insists they will send me a code between 24-48 hours but it never comes. One live chat agent actually insisted I recieved the email already. Another said he would reactivate my phone. It seems the live chat is completely dishonest and will say anything to get you off the line.

Can someone PLEASE help fix my issue so I can use the phone I legally own? I can't believe I have to fight for this as a customer for over 10+ years.
