Comcast Cable Did not honor package deal offered. newark, New Jersey

I spoke with an associate online through chat and was looking just for internet. The associate offered a considerably discounted  package of $35 a month which included basic cable and internet. Excited about the deal I was getting I accepted. 2 months passed and I was enjoying the service but received no bill. I then received a bill threatening to cancel my service if i did not pay $218 in fees. Confused I called Comcast and asked why I didn't receive a bill and they said it was sent to my email. I told them I didn't get it and asked what email. They said the one I sent up when I created my Comcast user account, I told them I never made one.
