I delivered a program, which I properly tested and everything is working fine.
After delivery buyer opened revision claiming software does not work.
I asked to show me error message, he sent nothing just keep saying program does not work.
I asked him to connect via Team Viewer, he said he will not show his screen and asked me to show the program running on my screen.
I did that.
It’s 10+ days since delivery is made.
He does not respond me back, just open a revision everytime I deliver, I ask him to tell me issue and allow me to resolve it. He replies nothing except program is not working.
What option I have?
