That is very good I think your experiences is good for me I encountered worst moment sometime ago,when I bid work on upwork after job approval,I complete the work successful but after all the time I spend for that six jobs none of the job was acceptedActually I have not considered any freelance site as the worst since I joined working online because I believe I earned what I worked for even though some.of the site don't pay me what I worked for but I earned to my satisfaction.
