DISSAPOINTED AND ANNOYED

I am honestly very disappointed with Rain, even after several calls trying to clear the issue with the sim card I received and have never worked ever i am still billed on a monthly basis. Now when I urgently need the 5G router I'm told I owe which is blocking my receiving the router. After even confirming from your side that I had never used the data as there was no coverage in my area this dates badc to 2022. How am I honestly expected to pay for something I didn't use? I'm still being billed as I'm always told someone will call to cancel yet still nothing so im basically suffering now because of an error on your side. WOW
