mygmc app and guardian app disconnected from email

[ehtx81]

I recently bought my vehicle and pushed the OnStar button to activate my free trial. For a few days everything worked great. I was able to use the MyGMC app and the Guardian app. Then, suddenly I was logged out and when I tried to log back in, the apps stated OnStar was not activated. OnStar is currently working on my car. I opened up the Chat and spoke with a representative who stated my email is not connected to my "profile". This does not make sense has I received the confirmation email of my trial and the December Diagnostic report to my email address. The representative even made me make another email and try that way, with no success. I'm so confused how my email could no longer be connected to my account. I have deleted and reinstalled my apps but no success.
