After a year on fiverr as both seller and buyer, I have to conclude that fiverr is just cheating both buyers and sellers.
As a buyer, refunds are not being made to credit card or PayPal - unless you raise it with your bank or PayPal. A process which might take another four weeks.
As a seller, fiverr might block your funds even after customers gave you a 5* review and marked the order as compete.
Taking 20 % commission and having to wait for 2 weeks (+3 days if order is not marked as complete) to be paid should make competent customer support affordable.
