I have to express my extreme disappointment. The cabinet that has been installed is not new, I can guarantee you. The wood is already warped by moisture and the whole cabinet is so dirty that I am really wondering where you found it. I'm actually quite concerned about all the bacterias that it probably carries.
And I'm not even talking about the big joke that your staff is: 6 people showed up 2 hours late without any notice. I had to call your office and complain to have details. 6 people for what? 2 were working, the others standing and watching, putting their dirty hands all over my clean walls and making stains everywhere. And they didn't even finish in more than 2 hours, meaning that I will have to go again and waste more of my time. Regarding the installation by itself, the metal pieces to hold doors are mounted upside down on one side and wrong screws have been put. Also, one scratch has been done to the marble under my sink, probably with a screwdriver. They are totally incompetent. Ridiculous.
This is, to be honest, the most unprofessional installation I have ever seen in my whole life. I expect 2 things from you and your company: competent staff who care about things and details, and a new cabinet, as this one is definitely not new, despite what your team keeps saying. I can't believe it.
