Inappropriate customer! He got personal, cursed and insulted.
The work was done 100%
The customer accepted and paid for the work, but then wrote that the "show more" button (which I did not touch) stopped working.
I wrote that I did not touch it and filled in the backup, which I made before starting work.
The "show more" button didn't work.
I wrote that I uploaded a backup and the button does not work and it's not my fault.
The customer confirmed that this was not my fault and that the button did not work before me.
Then he retracted his words and demanded that I fix what I did not break.
Then he began to insult and inadequately conduct a dialogue.
I asked constructively and without insults to write what he wants from me.
I didn't expect a constructive response.
The real name of the customer is Yatsenko Konstantin Gennadievich.

Unfortunately, the administration did not react in any way.
When I wrote that I was being insulted, the administration only warned him by copying points from the rules of the service into our correspondence, and he continued to insult.
In a review about me, the customer wrote "Objectively, the performer is a schoolboy." - I regard this as a personal insult and I believe that the administration should respond to public insults, and in response - "We do not interfere in cooperation if the parties have chosen to work at their own peril and risk."
I strongly advise against doing business with this client.
