We purchased Comcast's services without a contract. Comcast then created a comcast.net email address for our account without our consent. They then indicated that they sent correspondence to this email address indicating they were initiating a 2-year contract for our services. The correspondence apparently indicated that we had 30 days to opt out of the contract, or we would automatically be contracted with Comcast for 2 years.
I checked our comcast.net email for the first time today and found no record of this email. I printed a screenshot of my inbox and the two emails in the account.
I find this contracting certainly unethical and likely illegal. One cannot arbitrary create a means of communicating with a party only to compel then into a contract on an opt out basis.
