No Push Notifications via Mobile Data on 2 phones - Tech Support broke Mobile Data on one

Two phones - Samsung S10 and S22 - all working normal on Saturday. On Sunday Push Notifications via mobile data stopped on both. Today, Tech support spent an hour troubleshotting the S10 and somehow managed to disable Mobile Data and was unable to fix it. Then, after 1 hour on the call,  when he was trying something else I was bounced back into the phone queue. Spent between waiting for another support staff and going over everything that was done I spent another hour before I finally asked for a supervisor. Was told none available - all in a meeting but one would call be back withing an hour. Nope - 4 hours later called back in - after 35 minutes finally got to a supervisor and after a couple minutes was disconnected. Called back in again and no luck reaching a supervisor. Now have one phone with no Mobile Data at all and one with no push notifications. 6 hours on the phone today - almost 4 hours of listening to music on hold. First time I have had an issue with Xfinity Mobile in almost 4 years, but ready to leave at this point.
