There isn’t anyone on the forum who can contact you.
The forum is not staffed by Customer Support. Only other buyers and sellers are here. Even the forum moderators do not work for Fiverr. No one here is in charge of other sellers.
The seller did not have control over the refund amount. Fiverr automates refunds. It is spelled out in the Terms of Service that you cannot get processing fees back.
If you already submitted a Support ticket, you should see any replies in your email notifications as well. If you haven’t submitted a ticket you can do so here, but Support has already refunded you what you are due, so there may not be a point.
I haven’t heard of Fiverr refunding processing fees so I think you’ve been given all you will get, but you can try to pursue it with more Support tickets. You can close your own account. Go here https://www.fiverr.com/users/ellemckenzie/edit/account and see Account Deactivation.
Fiverr HQ is in Tel Aviv, Israel and Support is at a branch office in the United States. Since this is a global site, there would be no way to offer Support in all the languages used by buyers and sellers. I’m sorry you are so angry, but the Support system does seem to be working for most people so I’m not sure why you are having difficulties. There could be a bug in recent activity on the Support page. Check your email for responses and use the link I gave you to submit new tickets. Unfortunately, if that doesn’t work, using the forum to tell other buyers and sellers that Fiverr needs a phone number isn’t productive.
it is really clear in the Terms of Service that you agreed to. It states that you don’t get processing fees back. If you felt that was unfair, it was better to not agree to the ToS. I’m still sorry you had such a big problem, sincerely, but there just isn’t anything else the forum can help you with. Best of luck.
