How to change review

my client asked me to do a about us page but he didn’t gave me relevant information about the work.
he put the order without even consulting me,
when i asked about the details, he send me a link to a website but that website didn’t have any of the information i need.
later i delivered a document to my client stating the problem just to stop the countdown and I asked him to cancel that document and put on a revision or cancel the order,
but he didn’t do that instead gave me a negative review which gives me a bad impact for profile.
he agreed to change the review but he doesn’t know how to change it , is this the right place to give complaints or should i put it somewhere else?
