We were unable to reach you via text

HORRIBLE start to my service, so I'm going to stick around until I get the promo and then ditch this messy company. I've had almost 3 hours across multiple phone calls today with no resolution to my problem, with multiple service agents telling me to hang up to restart my phone and then not calling back as promised. I am getting near constant emails with the subject "We were unable to reach you via text" from Xfinity. These result from any attempt by Xfinity to text me. Today that's been trying to message support about activating my phone line and cancelling gateway that is shipping earlier than I requested. WORSE: it occurs when I need to get 2 factor verification for a login. I check that my phone number is verified, clear my cache, clear my blocked numbers, etc. on and on and on, and still THE COMPANY PROVIDING ME SERVICE CAN'T USE THE SERVICE TO TEXT ME! An absolute sham of a service, and I'm switching off as soon as I can.
