Vendor has performed some work using the supplies and materials that I purchased with his help. He installed a faucet incorrectly. Basically, still broken. He shredded screens while pressure washing my house. Left the same screens off the house. Painted the windows shut. Left the doorbell loose and the weather stripping off. List of undone goes on. Yet, he is demanding payment. How do I respond to this intent to lien? With my local courts, I want to respond.
