business mobile connectivity problems

We got Comcast Business Internet set up Back in Late April.  At the time they talked us into switching our mobile phones over the Comcast Business Mobile.  I checked and found out that both of our phones were deemed compatible by using the compatibility tool and our IMEI numbers so I agreed to switch.  We had to wait till the sim card arrived for my phone but my husband's phone was able to take the e-sim.  Anyway, we activated our phones on May 1st after the sim card got here.  Hubbie's phone activation went smoothly but when I went to activate the sim in my phone the web site kept the activate button greyed out and I had to call in order to activate my phone with the physical sim.

The Month of May seemed to be ok for the cell service, at least I didn't catch on to any connectivity issues if there were any (I might not always realize it isn't working if I'm not trying to make any calls.)

However, the beginning of June, I did realize I wasn't getting texts when multifactor authentication to log in wasn't sending me texts.  And then I wasn't able to send texts either.  And then I found I was not able to make phone calls.  I restarted the phone but that didn't fix it.

I tried to go to the web site to get chat support but was told that you can only get mobile support if you call them on your phone!

So, using google voice on my phone I called comcast business mobile support.

This is a MAJOR FLAW in the system guys!  If your phone isn't working, you should be able to get help via a different path than using the phone that isn't working!
Added Flaw is that generally phone support wants you to be able to talk to them from a second phone while you troubleshoot the phone that has the problem.  So now I'm having to get a second device AND phone service JUST to allow me to get the Phone Service I purchased from you working?!?!?!?!

Anyway, I now have 16 support tickets plus 2 trips to the local xfinity store dealing with this phone problem that started June 2nd or before.

I have been having to reset the networks and/or restart the phone every day, sometimes multiple times a day.
We have already gotten a new sim into the phone (that is what the 2 trips to the xfinity store were because the online activation locked up and they couldn't help me on the phone and when I went into the store the first time they sent me away saying my ID wasn't good enough, I would have to have my Husband there too with not just one but TWO forms of ID in order to activate a SIM card that they sent us for my PHONE which I had with me.  Unfortunately my husband was away on business so couldn't come into the xfinity store with me.)  I called support again the next day and they confirmed that for a business account, I should be able to show my ID and get the sim card activated.  So I made arrangements to allow me to drive to the xfinity store again, this time luckily the associate was able to activate for me.

But the next day, I had issues again.  So the problem isn't the SIM card.
I had one support agent on the phone who kept insisting my data wasn't working because I had used up all my data, and when I told here the account was unlimited, she claimed that it was because signal wasn't good because of buildings or something, No, the phone is showing multiple bars and 4g LTE I should be able to use data, then she was telling me that I needed to have more up to date software and gave me the phone number for samsung.

Just today, I called to complain about this constantly having to reset the phone and missing calls etc and the guy said he would call me back in a few hours.
HUH?  So how is that supposed to help the situation?  If my phone is working, then what?  If my phone is not working, you won't reach me, how does that help the situation?

I'm so close to moving our Mobile Phone service elsewhere as this is getting ........
