We were hired on as an electrical subcontractor. On a remodel that was supposed to take 6 weeks but turned into a year. We had an original contract for a few rooms in a residential property but the home owners asked our GC to add more to our original contract so there was a change order, then another contract for a panel change, then another change order but a verbal agreement that at the end of the project we could turn in all the change orders. Well the supervisor employee of the GC who made the verbal agreement got fired at the end of project 2 days before we agreed to send in the remaining change orders. We explained to the new supervisor employee of GC our agreement with the fired supervisor and he said that if it was never in the original contract then we needed to take the bill to the home owner. We reached out to the fired supervisor who verbally asked us to do the change orders and he signed a statement stating that he gave the approval for the change orders. Since getting that signed we have tried contacting the GC. He has ignored our emails, calls, and text which forced us to send a notice of intent to lien. That too has now been ignored. So, I reached out to the home owner while being ignored by the GC and let them know the situation. They informed me that they had paid the bill in full to the GC and that we needed to discuss the matter with the GC. We reached back out to the GC with still no reply, we sent the home owners a notice of intent to lien that was ignored, sent the home owner emails explaining our situation and it was ignored. I need legal advise on moving forward. We cannot afford to not be paid for the materials and labor we put into this project. Thank you so much for your time.
