Lumber Liquidators Installed wrong product and faulty stair nose and refuses to correct the issue Columbus Ohio

When we first went to Lumber Liquidators everyone was so helpful in picking out our flooring. Then the nightmare began. The guy who came to measure was literally in our house for 5 minutes and the ONLY thing that he discussed with us was if we wanted the closet included in the install. He then apparently took it upon himself to order quarter round and never discussed anything about our baseboards with us. They installed the flooring and put in the quarter round up against our existing baseboards which with the difference in colors looks horrible. The stair nose is loose and moves anytime you go down the stairs. I called the store immediately after install about the stair nose and the quarter round at which time Brandon indicated that it was HIS fault for the quarter round because he didn't discuss baseboards with us at the time of order and that this would be remedied even if it meant reinstalling the entire floor. Never heard back from him again. I have gone to customer service and even to the manager of customer service. I was contacted by customer service a week ago today reassuring me that they wanted to remedy this and that the assessment team would contact me and come out to the house to see what could be done. I have yet to hear from anyone! This is the absolute WORSE customer service EVER! I will NEVER deal with Lumber Liquidators again. They will be "at your service" until you need them to fix their work and then you can forget it! They will disappear!
