I had a pretty bad experience with a client named as on Fiverr "Mr_AJ" he asked us to create a plugin for reviews section manipulation on Woocommerce product page, i had created a plugin he asked for extra work in the same project as i told him that it's out of scope task and it will be in another order he said i wil cancel the order as a new seller on fiverr i have compromised and did what he asked for. As the final build was created i delivered to him he approved the order with 5 star rating i was happy that finally i didn't end up getting bad review so after 5 days he asked the support for refund and got the order cancelled now he is using the plugin in his website and got the refund as well. The customer support is favoring him how it's fair to us ( Sellers ) literally quite dishearted from fiverr as sellers what rights do we have, are we just here to get scammed from such goons? and the customer support favors the buyer. if the buyer is paying the service charges, are we ( sellers ) don't pay the service charges. why does so much discrimination?
