Regular Phishing request with imposter email says Billing Issue

Every month I get an email from a random email address that is trying to impersonate Xfinity Billing saying that my payment didn't go thru.  This email is is entirely bogus and it requests me or you login to a Google Doc, to update my payment information. This happens on a regular basis every month for the last few months. I have  consistently reported to the abuse@xfinity.com, Google, the DNS naming provider for the source email host, FTC, FBI  and IC3.

So why can't  Xfinity training an AI based email  filter to detect and suppress this type of email?
