OnStar Telematics module - no dates for backorder part is unacceptable

I’m with you and also so frustrated. After two months, I was also told today that it’s a back order and no eta. I’m in a Tahoe and my module thinks I’m in a Suburban. I had to explain this situation to many different people, multiple times during my free month, for anyone to even figure out what the issue was. I’ve been told 5 different things would fix it by onstar, yet it’s still not fixed 2 months later (headed into month 3). Dealer was supposed to try to reprogram the module I have, but said I needed a new one without even trying. To boot, Onstar even told me to go ahead and sign back up for services after my trial ended (I was told my free plan would be left on until the module came in, but have determined this was a lie), but when I did, it still wouldn’t work. Why did it work to start with? Why can’t they’re just do whatever they did when I purchased it over 2 mos ago so I have my services until it comes in? I finally got a new GM vehicle and upgraded from my 2008 suburban. I almost went with another make, but gave GM and Chevrolet another chance, only to be stuck with this mess as the reward. These features are a huge part of the reason that I made the purchase to start with! No eta is beyond unacceptable and now I’m auto paying (and likely will be for months to come) $50 USD a month for a service I can’t even use!!! I want some answers, not a response of back ordered and No ETA!!!
