Dangerous Situtation

I have low hanging cable line across my backyard, less than 6 feet from the ground, because the cable became unhooked from the pole.  I have contacted Comcast twice, and told twice (after 20 minutes of hold) that someone would contact me within a few hours or the next day. Never happens.  Somoene is going to get severly injured and you are going to get sued due to your negligence in failing to respond after you were put on notice.  This is truly insanely stupid and negligent behavior.
