Ah…bad buyer experiences…
My worst was a guy who wanted articles + royalty free images + video intros. This is fine usually, as I can make $30 out of such an order. However, he wanted it all for $5 and told me all about how poor he was until I agreed.
I delivered all work in 24 hours and he ordered a second article. After this one though, he asked if I could create an account on his website and upload them for him. Being super busy at the time I said no, not without at least one gig extra as he already had a great deal.
At this point the buyer turned very hostile and stupidly I created the account and tried to upload them anyway. The only problem was that his site was slow as hell and in the end I gave up after 20 minutes as it was simply way too time consuming for me.
As politely as possible, I therefore said look, I don’t usually offer this service and you have a really amazing deal here already, moreover, I would do this, but not if it’s going to add half an hour of time.
The result? He sent me a crazy message saying he could already sense that I wasn’t committed to his project, changed his previous 2 5 star reviews to 3 stars and left me feeling quite shocked to say the least.
However, it didn’t stop there. A week later, he started emailing me on my personal email which he had taken from the account details I had used to join his site with (as I never disclose personal details for obvious reasons), asking me for more work in return for him changing his reviews back to positive ones.
In this case, I got in touch with CS to report him and blocked his email. Moreover, now I never, ever offer extra services for free.
In fact, Fiverr can be a real eye opener when it comes to how bitterly and weirdly other peoples minds seem to work sometimes.
Anyway, don’t worry too much about your 4.5 star. You could always message this buyer to ask where he feels the work you have done as fallen short and if there is anything you can do to fix this.
