I did annotation work on buyer online tool.
when i completed my work and marked my project as delivered.
Buyer replied in my chat window.
Please repeat work as some other annotator deleted your work.
I rejected to redo as that was not my fault.
Buyer created dispute
Bad customer support from fiverr as they supported buyer , although they read messages from my chat.
and at end they said provide us a proof in form of screen shots.
and they cleared dispute in favour of buyer
Advise to sellers
When you are working on buyers tools , do have proof of your work in form of screen shots
