Express Flooring review: Product and service

We hired Express Flooring to complete a whole house flooring job at our house 8/2022 after a small water leak and since our flooring was more than 2-years old the Insurance Company gave us the money to change the entire flooring of the house. The salesperson stated that all we need to do is have a level floor for the floating vinyl we had chosen. The work started 9/2022. We found mold and had the work suspended and the house was cleaned. The work commenced and the Installation Manager Tony was onsite and noticed that plywood was been laid down and did not say anything about it. The work was completed sometime at the end of 9/2022. Two months later the floor in my husband's office started buckling and we called it. They sent someone out to inspect and that person stated it was my husband's office chair that was causing the buckling and that we needed to place a place office chair tarp or some type of rug. We stated we specifically purchased that flooring, so we did not have to do that. So, at this time they replaced the vinyl in his office. Two weeks later the flooring that was replaced started buckling again, but this time it was throughout the house. They sent another inspector; is time it was Lisa (Corporate Office from what I was told) came with a different inspector. We were told that the flooring would be replaced, and we were put in contact with Mary. Mary started to state that the problem was that the floating floor was placed on top of plywood, and it is the flat of the contractor that laid it not theirs. We stated that Tony was there and saw the plywood being laid and did not say anything. After two-month Mary came out and stated that the flooring would be replaced, they would take it down to concrete. It has been 4-months since then, and on 8/24/2023, the flooring was lifted, and we have been left with plywood only. No one is responding to my calls and yesterday I was told "Mary is trying to get her act together she will call you by the evening." No call yet. I call the customer service number and I am told I will have someone reach out in 24/48 hours and no does.
