The only negative review, I have gotten was from a buyer that hadn’t read the description. She thought, that in my $10 gig, I would fill her page with content and manage it.
Those were her words:
“No worries, it isn’t your fault for the review, you did a great job, but I thought that the pages are going to be filled with content”
Sadly, customer support was not able to help to delete the review.
