Rain No Service for real

I have two rain SIM cards. One of them (the unlimited one) suddenly says “no service” and “device is offline” in the My Rain website. We have inserted it into multiple 4g devices (that it had no problem working in before), rebooted them, reset/changed APN setting, manually selected network (it doesn’t even give rain as an option anymore) and NOTHING has worked. I held forever contacting the call center and non of my queries lodged have been rep**** to. The second sim is working fine so it can’t be the network. I don’t know what to do with this sim. Should I just cancel it and cut my losses??
