Another Bad Telematics Module

I own a 2025 Chevrolet Equinox.  My OnStar was spotty but working in March and April, but now went completely out.  I called OnStar and they could not connect.  They said it was probably the telematics module is bad and I needed to take it to the dealer.  Took it to the dealer and after two days of trying to get the OnStar to work they said the module needed to be replaced.  Fine, but the module is on back order with no ETA.  I’ve read online that it could be up to a year.  This is our only car and I pay a lot for my subscription.  I do so because OnStar is something I rely on and now you tell me I’m without it for weeks, months… who knows?  Plus I’m spending $$$ for nothing until it’s fixed.  Someone surely has an idea of when I can get this fixed…don’t they?
