How to deal with a buyer?
For whom you have invested more then 6 hrs for “$5” custom offer, even gave a “gig extra” for free.
After “Fiverr” mark the order complete and he/she appears from nowhere and asks for a refund or threat you of a poor review, treat you like a garbage.
Even then you do revisions to keep the client happy and at the end client give you poor review.
It happened to me recently, for the first time.
