AAbsolute, instead of you fishing for a name from someone here, why don't you tell us a name of a person you absolutely pissed off who would want to see you fail. Then, if anyone here knows this person, they could bring it up in casual conversation;
"Hi upset person, how's your family these days?"
"Really, that's nice. Little Jimmy doing well in school?"
"That's great, primary education really is the cornerstone. Hey, tell me, why are you trying to run down Chambers street builders?"
Possibly you misread the intent of those(me) suggesting you take this to PM. Confront the person directly, in private and get it done with. At this point, if I was looking for a builder, Chambers street would not be at the top of the list due to this thread and your other one about your stuff in the ground. Too much drama. I'd be worried you'd be dragging every little thing around forever. Obviously, not sure that would happen, but my confidence in your discretion is not high.
You cannot be the only builder that has problems with people on the job, but you are the second one I remember that's brought his business to this board in this fashion. The other was a disgruntled painter, if memory serves. I won't be the one to post the dead horse gif, but I bet it's close to someone's enter button.
ymmv
