Business ProfileforStayDry Basement Waterproofing

StayDry place a lien on my house in 2018 because of non-payment. The original reason was work was not completed, and after talking to the company they realized they did not complete the work. They then came to finish the job and I was happy with it, and paid them in full.Now the issue is that the lien they placed on my home has not been removed. I have contacted them via email and over the phone. They originally sent me a receipt that says **** but I owe still. Since they originally sent me the receipt I have been trying to get a letter stating the lien has been removed. But now after 3 months of trying, they refuse to answer any inquire I have about it. I email them have proof they read it, and no response. I gave up calling them because they can't seem to figure it out. It was really easy to put the lien on but they can't figure out how to remove it. The issues I am having are because of the Lien I have not been able to take advantage of a mortgage opportunity, and missed a business opportunity. My bank says the stuff I have will not suffice as documentation because they have not gone through court or been recorded at the county level.This is all about a lien that needs to be removed. And the fact they refuse to respond to any inquire.
