Emails have stopped arriving gain!

I have been reading the forums here. Despite the fact that the "technicians" at "support" insisted to me that they've never heard of emails being displayed correctly in the Xfinity browser but not being delivered to my home, I'm finding dozens and dozens of complaints about the very same thing. Are they lying to me or just incompetent?

The "support technicians" wanted me to "reload" my "Outlook". I kept telling them I have a Macintosh computer and use the Macintosh mail application, which is part of the operating system. I'm not inclined to re-load my entire operating system, especially now that I know that hundreds, maybe millions, of customers are having the same ridiculous problem.

This has been happening on and off for quite some time. Sometimes, two days later, all the "missing" emails come flooding into my inbox. I'm running a small business, I can't have this be happening. Unfortunately, the only broadband option at the moment is the ancient coax cable owned currently by Comcast running along the telephone poles at the back of our yards.

This is unacceptable. The first broadband company to run fiber optic cable down my block will get my business. I doubt Comcast management is competent enough to understand this.
