I am an Interior Designer. The contractor that I hired to renovate my customer's bathroom was unprofessional, did not complete the job, did poor work and has charged me with additional fees. The contractor sent my customer an e-mail slandering and degrading my name and my work. I emailed the contractor with a payment offer, he did not respond. He is now attempting to extort money from me by threatening my customer with an Attempt to Lien through Levelset. I have disputed the inflated fee he is attempting to collect from me via Levelset. How is this dispute settled on Levelset? How can I prevent a Lien and is the Lien legal? My customers did not contract him to do the renovation, I did. Please respond, my customer is threatening to file suit against myself and the contractor if this is not resolved immediately. Thank you
