Bro Fiverr will not do this . But if fiverr do this things that when a buyer will contact the fiverr support and tell them to cancel the order because they have placed order by mistake then fiverr cs will cancel but our cancellation rate will not increase . If fiverr do this then I think it will help us .Or if buyer cancel the order then our cancellation rate will not increase . I think at least fiverr should add this system .
