Onstar forces auto buyers to sign up for their services under the facade of "three free months". The clear hope is that you forget to cancel which allows them to quietly bill your credit card until you discover their scam. The dealer told me they should have sent an email indicating the paid subscription was beginning in February but a search through numerous OnStar emails revealed no such notice. When I called to request a credit I was told someone would get in touch with me within 48 hours. After waiting a week or so I called back and was told it could take up to 30 days to review my request. After about 45 days I called back and during that call I was read a maple syrup coated rejection based on their claim that I received uninterrupted OnStar service and therefore didn't qualify for a refund. I complained about their unethical billing practices and asked them to have a supervisor contact me so I could escalate the complaint. I was told someone would be in touch with me within 24 hours but a week has passed with no contact from OnStar. In my opinion OnStar billing practices are subversive, strategic and unethical. I will never use their services nor will I never purchase a vehicle if forced to sign up for OnStar.
