5G home internet - interruption of connection -support was contacted

We started our 5g home internet with T-Mobile about 6 months ago, it was working fantastic for about 4 of those months. Last month near the very beginning we started having an issue where all of our devices are connected to the modem, but no internet connection is available, the only fix we have is to unplug and restart the modem. We called support yesterday, they told us about the new 2022 modems and that many customers have been calling in with this issue. After getting our new modem yesterday we still have the same issue every 30 mins a break in our internet connection begins and we need to re-start our modem. I called support again this morning to which they again said many customers are having this same issue. When I heared that a bell went off, "T-Mobile has a massive server or processing error with all of these modems, not just the old one we were dealing with." They proceeded with the basic turning the router off and powering it back on, the support told me he was doing some sort of trouble shooting (to which he was supposed to send a list of troubleshoots to use if it were to continue, he never did) I got a call about 20 mins after to make sure my internet was still working, I told them yes and that it hadn't even been long enough for us to have the issue again, they were happy with that and gladly wished me a good rest of my day. I am so beyond frustrated with T-Mobile right now, they honestly should be giving customers a refund of last months billing cycle and get this sorted for all the hoops we have to go through in order to even have a half hour of this so called premier coverage of 5g home internet, it's really feeling like a bad joke and customers are just supposed to deal with it.
