Problem with ESIM and phone

I switched 3 lines to Xfinity mobile in the beginning of May, this was under the belief that xfinity would be saving me money. During the initial switch, one of my phones they claimed had a ESIM issue that was allegedly fixed.  The phone worked correctly for 20 days or so and then I found I was being charged for 2 extra phone lines. In the process of getting rid of those 2 extra lines I did not ask for, something got messed up and the 1 phone that had the ESIM problem hasn't worked since at least May 28th. I've spent hours online, on the phone, and in the store with no resolution, just excuses.  I have had several ECM tickets created, with multiple promises that the ticket would be resolved, "I have reached the right person and the phone would start to work again. It will just take 72 hours for the ECM ticket to resolve it, then oh no  72 more hours after the ECM closes then it will be fixed" This has all been false. Has anyone else been through this nightmare with xfinity, and who was actually able to fix the issue? I'm tired of this and fed up with this poor level of service. 

Now a surprising new turn of events

My Wife received a call to day from someone claiming to be from xfinity. The caller was in a call center judging by the background sounds, this person claimed the phone issue we were having was fixed (it still is not) and that for $2 we could get a free month of service for our troubles.  At no time did we tell him we had a problem with one of our phones he seemed to already have information. The phone number was spoofed with a caller ID indicating Xfinity. This makes me reasonably suspect that the outsourced call center has some undesirable people working in it that may be taking stealing information and sharing it with some of these foreign scam centers, or that xfinity mobiles' service is that bad that they randomly called someone with existing phone problems thinking they could get one over on us.
