ROMARO

I just sent my StarLink dish back. It worked, but I found that I could get a cellular service at my location that was cheaper and faster. I got an RMA for the dish and modem. I have a SHORT WALL MOUNT, a MESH WIFI ROUTER, a CABLE ROUTING KIT, and a ETHERNET ADAPTER. All in unopened boxes. It doesn't appear to me I can get an RMA to send this equipment back to Starlink for credit. Can you confirm? If I can't send it back to Starlink, can you suggest an aftermarket place to sell it?
