Getting hundreds of spam e-mails. What are you doing to stop this?

For the past week I have been getting 100's of e-mails daily that are spam, phishing, things I have not signed up for.  I talked with someone last week and they said it would be fixed.  It continues.  I will probably be dropping Comcast thanks to the lack of help or the ability to talk with anyone.  Oh and the AI assistant is worthless when I ask to speak with an agent, it just keeps throwing the same no assistance line at me.
