Ineffective spam following

I've been getting swamped daily by spam reporting to be from Xfinity for months now.  I have forwarded it all to [Edited: "Personal Information"] and [Edited: "Personal Information"] but nothing has improved. It's obvious spam, easily detected by looking at the return address, or the fact that every one starts with "Surprise in your inbox!".  Yet Comcast/Xfinity has done nothing about it. This is the easiest type of scam to catch, but you're just funneling it all through.
