High saturation node, slow internet speeds, intermittent drops and nothing they can do?

Same kind of problem in 92691.  Lots of correctables/uncorrectables on cable modem, although data rates are decent (usually 100Mb/s for the "150" plan).  Most annoying are the dropped connections which kill the VPN for work, and kill online gaming (kids go crazy because a dropped connection looks like you quit a match, and you get banned from the game for a period of time!)  Checked connections as best I could.  Emailed cox.help@cox.com just now.
