I am a level two seller on Fiverr and I've been working on this platform for almost three years without issues until now. A client initially satisfied with my work on his website returned for a new website, and despite additional requests during development, I completed the work and delivered it. He happily accept the delivery.
Yesterday, three weeks post-delivery acceptance, he requested additional work. Despite completing it out of courtesy, the client faced an issue: he couldn't see the main menu on his website due to excessive browser zoom (instead of the main menu at the top, all he could see was a menu drawer like you see on a mobile version of the website). I explained the solution – to zoom out slightly – but he struggled to grasp this, consistently blaming me for an incomplete website despite earlier acceptance. To make sure there was no issue in the website I shared the link with more than 20 of my friends and asked them to send me screenshots. And as expected everything was working fine but the client kept calling me fraud and was very rude and unprofessional.
I contacted Fiverr support to ask for assistance regarding the behavior of the client, but my request went unanswered. Today, I received a warning from Fiverr, and it is highly likely that the same client reported me. I find it unjust that Fiverr provides significant leverage to buyers, potentially enabling them to intimidate sellers in doing free work. This situation worries me about refusing additional unpaid work from clients because as far as I know there are three strikes and its out.
What would you suggest I do in this scenario?
