Bad telematics module

Our telematics module went out on our Cadillac Optiq  April 2nd after an OTA update.
We went through onstar for a diagnosis, were told they could not connect, and to make a dealer appointment.  The dealer had no EV service appointments available until April 27th. The dealer confirmed it was a bad telematics module and placed an order.
We are stuck with no onstar, no gps, no garage opener, no wifi, no supercruise, no access to music libraries, no scheduled charging, no access through the app.
This is coming up on 2 months without common vehicle features and no ETA on a fix.
Very disappointing that new modules are not being directed toward current owners.
