Stop calling to sell Xfinity Mobile

I am an internet customer and I do not want any other Xfinity service, particularly Mobile. I am being called multiple times a week after stating I was not interested. I am on the Do not Call List and have update my privacy preferences. Do not solicit and harass existing customers for additional services. Its bad enough that you force your employees to do sale pitches on every call making their job miserabl by [Edit: Language] your customers.
