Scam Email from Xfinity Service

Have had weekly emails stating I needed to update my card information to pay my bill. Last night I received a final notice that my service would be suspended and that Xfinity was sorry to see me leave. Very authentic email, using the same fonts as xfinity. I knew my account was not connected to card and saw payment post in August therefore did not worry. It did make me question again do to the authentic looking email and consistent emails. Beware!!
