I got a 20 day lien notice sent in to me and signed it disputing. The company never sent an actual bill to my house for services and billed me way more than the initial verbal agreement for the scope of work. I do not want to pay them the amount they are putting in this lien due to never having agreed to an amount above the money verbally agreed upon. They will not send me any contracts I have signed as I asked them for these. This looks like a very deficient lien but, I don't want to have it against my property. Can you provide any assistance?
