Telematic Control Module needs replacement, but backordered with no ETA?! UNACCEPTABLE

Good to see the moderators on here copying and pasting the same reply. I don't think it matters if the vehicle is under warranty or not as mine is under warranty and I am getting the same old song and dance everyone else is. I called last week, and the dealer still has no ETA. I asked if there's a way to elevate the issue and they mentioned the backorders automatically ping GM. It's obviously not helping so maybe one of these moderators can help!!??
