No More Mrs. Nice Guy

I am a female, I am brunette and I am reasonably intelligent....so why do people look at me and think that I am going to buy their lame excuse for lack of PROPER workmanship?

We have black distressed cabinetry in our kitchen and they are half matte half shiny. We have had 4 meetings with the cabinet company that went (summary) something like this:
"they did it"
"we didn't do it, your manufacturer did it"
"impossible, your cleaners did it"

Then, the fingers point to me, "she did it".
They are trying to say I used some cleaner on the cabinets as high as I could reach, hence the half shiny/half matte finish.

First off, I am not a moron. If I am going to wipe down my cabinets, I am going to wipe them ALL down, not just half way up.
Second, SERIOUSLY??? If I did it, why would I bother calling them out 4 times to fix my mistake AND have to wait each time, at home, with a 4 hour "we will be there between..." window? That is 12 hours of my life I could have been utilizing in a more festive way.....

So, today, No More Mrs. Nice Guy came out of my body. It was scary, I watched her, from a distance, she is intimidating.

I told this putz that I only use a dust cloth, no chemical solution and despite the fact that I am only 5'8, I do, indeed, own a step ladder and have over 25 years of cleaning experience.
Going on to mention that manufacturers have defects and if you think for a second that I am going to buy this bologna you are trying to sell me, you are mistaken. I may have blonde streaks in my hair, but do not confuse that with STUPIDITY, Mr. beef jerky!
In addition to owning a step ladder, I own a brain (imagine that), so bring back somebody who is prepared to FIX the problem, and if they cannot fix it, bring me a check signer from your company, because they will be writing me a fat check for these lousy cabinets + 12 hours of my personal time...
