report safety issue

How do make an actual report of a damaged Xfinity line: not assistant, not "chat", not "multiple choice" options that do not explain the issue? There is a tree limb that has fallen on an Xfinity cable line near our home. We know it is Xfinity since DTE came to check and determined that's what it was (and they actually let us leave a voicemail and returned our call in 2 hours!!!!). We do not have an interruption in service, but would very much like to report this so a crew can address it before it becomes a larger safety issue.

How do I reach someone who can take a report?
