Installation done wrong. Can find NO human to talk to.

I had a new cable/line installed.  When the installers laid if out, it was perfect.  I left them to it and after they said they were done and I thanked them, i looked and they had moved it under a tree  and left not slack to account for burying it.  Burying it will bring it even closer to the tree, and they may not actually be able to bury it there.

I have tried all the phone numbers I can find to report this and have it redone.  I guess no humans actually work for xfinity.  Just some no-so-smart ai things.

I need someONE to talk to.  This could be resolved in minutes with an actual person.  I've spent hours trying to get those few minutes.  Insane.

Supposedly people from xfinity are on here.  Please point me to where I can actually talk to someone.
