Unfortunately for over a month now they have not even let us know any information in regards to what’s wrong. That’s why I need as much info I can find to bring to there attention in regards to the possibility of what they have wrong there.is that loaded or unloaded voltages?
Thing is they possibly have blown fuse on a capacitor or maybe just need to connect certain single phase services to a different phase and it possibly clears up the balancing issue. POCO's around here would be willing to try to solve this problem.
Under load But voltage doesn’t move too much load or no load.
