I changed my Xfinity/comcast password because my email contact list was hacked. I am not receiving any email from my contact list.

I am only receiving emails from the emails in my JUNK folder.  I worked with Mo at Xfinity this morning and he sent 3 emails to my comcast.net email and I only received two of them.  He tried several things (don’t know what) and I still didn’t receive his latest email.  He gave up and told me he’d send it to Tier two.  I needed to reply to a text he sent, but it was just a survey.medalllia.   I haven’t heard back from anyone!

What do I need to do?  I am using Apple mail on my Mac with the xfinity comcast email.
