IG...thanks for the heads up.
When you hover your mouse over the link they provided in your original email (the one that says
www.comcast.com here) and look down in the gray status line of your computer, did it point to comcast.com or some other nefarious address?
On the copy/paste here the link does indeed point to comcast.com.
