Fiverr only allows for good feedback to be left on sellers. The only time it will allow you to write a review is when your order is marked as Delivered or Complete.
Ask yourself what do you do when you are unhappy with your order/designer. 99.9% of people will answer with "cancel the order". Because why would you want to pay for something that you are dissatisfied with……. I thought its was a little funny that ALL the sellers have 4+ stars but now i understand why...
In my situation I needed a logo design, I had an image of what I wanted no creative input needed.
1st designer canceled the order on his end- couldn't leave feedback because the order wasn't completed
2nd designer just told me they couldn't help me and left the order sitting there without canceling it. Once again I can't leave feedback because the order wasn't completed.
