Update component in Joomla

Attention, clients! The project will not be restored if the changes you made are not satisfactory Or will require additional funds to restore it. My task was not completed and I tried to shift the blame for my lack of skills onto the vagueness of the task. I spent a lot of my time on a fairly simple task.

RUN AWAY!!
The client is playing with the performer like a cat with mice.
I updated the component for him, needed to update the design.
Mentioned admin panel, etc. Screenshots, etc.
--No, make it "beautiful" for me
I say -- review the component and tell me what exactly to change?
---No -- you should understand everything yourself

Well, in short: took my work, turned to arbitration, and I: wasted time and was left with nothing.
