I ve been there for few months and finished about 10 projects, out of 10 i got paid only for 2 of em although i finished all 10 on time. Employers are not obliged to close projects and release milestones EVER so the argument regarding that milestones are a security measure which keep both the employer and employee safe is FALSE! Projects with open milestones can remain open to eternity and never close on itself! Beware of that website as you will spend lots of time delivering SLAVE work for people you cant ever trust! I also posted tickets to the tech support and they gave promises to contact employers on these ever-open projects. I NEVER GOT ANY FURTHER FEEDBACK.
Hello Miroslav, my name is Lara and I'm from Freelancer.com. I understand how exasperating it can get to work for a project and not get paid. This is why we always recommend freelancers to only start work once there is a Milestone Payment created for them. This gives the freelancer the feeling of assurance that there is a payment waiting for them once they have fulfilled the requirements.
I respect your opinion, but hopefully, you still give the site a chance in the future. Take care!
