Existing Customers Treated Worse Than New Customers

I think it is completely ridiculous and poor customer service to treat new customers better than existing, loyal customers.

I contacted the "loyalty" department but still was not able to get as good of a deal as a friend who signed up as a new customer.

It seems Xfinity would rather lose me as a customer than treat me as important as a new customer. I have been a vehement defender of Xfinity, but no more.

If I cancel my service with Xfinity, how long until I am considered a "new residential customer" again?
