i think i received phishing email supposedly from Comcasat is it legit?

Greetings @Murf1954,thanks for taking the time to reach out, I hope the week is starting out smoothly for you! It sounds concerning to receive emails about your Comcast payment, especially when your bank shows the payment went through. It's wise to be suspicious, as this is a common tactic used in phishing scams.
