Hello, I hired a window company for a patio door and front window. They were to be made to my custom size. I paid $3k down. The company sent out a tech to do a measurement on 4/26/21 and no work has been done since. Installation has been cancelled on me twice on very short notice and I cant get to speak with a manager or get my calls returned. I have paperwork that states the installation will be scheduled when all of the product is available. Both install dates were cancelled because the door was not available yet. Would this be a breach of contract on the window companies part? If I'm able to get my down payment back from my credit card and tell this window company I want to cancel the project; can the window company place a lien on my home?
