How can I get my money back from a well k now cabinet chain

I hired a well known cabinet company to install all the cabinetry in my home after purchasing the cabinets from them. All the paperwork I was given had "All of their Installers are certified, licensed, and insured"..The company sent a crew of 3 men..To make a long story short..The men that was sent into my home weren't certified licensed or insured. I never signed any waiver or document signing off for group of Installers that would make my life a living nightmare. They walked out and never finished the install this was June 20, 2020. I HAVE NOT received a refund nor has any of my cabinets been switched out. Had a 3rd party cabinet inspector come and look at all the manufacturer defects along with the damages the Installers caused during assemble and install. The inspection report concluded there was a manufacturing stain issue. He also noted there were some damage due to having the cabinets transported incorrectly. There were also many issues with the install itself..what was done.. The company still has done nothing...no refund..they have not sent anyone to complete the install nor have they fired the contractors. All my husband and I done was pick out and pay for the cabinets. It was the company's cabinets and their installers. They keep telling me ...the cabinets were installed and our terms and conditions clearly states no refund after being installed ..Their contractors done the work...They are holding me liable for their unprofessional. Non licensed, certified,and insured contractors. I asked for a full refund on the 2nd day of install. How can a company not follow their own terms and conditions then hold a customer responsible for their employees that were left without any supervision. This has been a horrible past 8 months..I just want my money back so I can get new cabinets and my life back. Thank you for your time. It's greatly appreciated.
