GM Community Terms of Use

I have been billed for the last 3 months for a charge of $8.53 for Onstar.  I have called the customer service number at 888-466-7827.  They claim they cannot help me so they give me the number for loss prevention at 888-489-7359.  I called that number everyday for the last 7 days.  All you get is a voicemail message and NO one every calls you back.  I was told to email onstarlossprevention@onstar.com and NO one replies to your email.  I have emailed 3 times.  I called again today and was disconnected.   I HAVE NEVER OWNED A GM VEHICLE.  Do I have to go on every social media platform and tell all my followers how Onstar is stealing money and conducting fraudulent business practices?  Do I have to call my State Attorney's General Office and file complaint?  This is outright theft.  I never authorized the charges and have never owned a GM product.
