Rain 5G customer support

On Thursday, 27 May 2021, my Rain internet service was interrupted. I first attempted to chat with them through Facebook messenger. When they responded I explained to them that the modem was connected to the network but their was no internet. Even knowing that this wasn't a signal issue they preceded in sending me the steps to optimize the network signal. This happened several times. After a week of back and forth they finally dispatched a technician, you also noted that this was not a signal issue, and he spoke with their back-end tech and they said it had something to do with the PCS CDMA, or something like that, and they said they would look into it. Now after two days, they haven't done anything or given any feedback on the matter. I would think that they would at least try something like a new sim card, or different device. I have nothing but raving reviews with my experience using Rain's 5G offering, but there customer support is awful.
