Telematic module is out

I hate to hear this.  Unfortunately, the module is trash and should be a recall with upgraded components.  I finally was able to have my new module installed two months ago. After, the installation, I was told to push the blue button to reactivate it. I drove my truck down the road about a mile to get fuel. While I was filling up I tried calling. After pushing the blue onstar button the functions responded like it was supposed to. It started ringing and ringing and after about a minute it stopped ringing and said try again. I didn’t think much about it because all my functions stayed working on my dash etc.  about a week later I had a check engine light come on and I tried calling onstar to get a diagnostic report, again no answer. I then tried calling SOS, no answer. After a few minutes I received a call back from onstar asking if anyone was hurt etc. I explain that no one answered and continued to explain what issues I was having. After sitting on hold for 5 mins the gentleman returned and said everything was working fine on there end. Being frustrated I hung up and call my dealership back.  Again, I had to take my truck back in. Come to find out the new module they installed was bad. Now, I’m waiting for a new one to come in. Supposedly, the modules are on back order. Humm I wonder why? Maybe, because they are junk and have tens of thousands to replace.  I wish you luck.
