Charged for "free" promotion. Again.

How did you get an executive resolution because they are doing this to me on a "free" apple watch. They told me I have to call every month to get the charge removed from my bill because on their end they did not apply the appropriate promo code. I do not think I should have to call for the next 30 something months to get my card not charged. I told them to remove my auto pay and just bill me and I won't pay as that is ridiculous. I have been a customer for over 18 years and feel completely scammed over something they pushed down my throat after I repeatedly told them I didn't need or want an apple watch. I finally caved and said I would give it to my son who isn't even using it. It is a complete scam and I work at a law firm and threatened a class action lawsuit as I now see all these threads with others being taken advantage of. 

I sent a direct message to support following the instructions in the other post by the Xfinity employee in this thread and demanded it be taken care of. I tried to provide documentation but it was conveniently impossible to find in my account, so I said I just wanted to cancel, and that's when they had me provide contact information for escalation.

Most people likely don't notice the wrongful charges, so they probably make more money by lying than they lose by settling with people who call them out on it.
