I have been a freelancer for a very short time with UPWORK and no where are you able to reach out for assistance as a "Freelancer" to make sure you get paid. I have recently been engaged with two doctors from Washington to solicit and create a sponsorship package for their event in Martha's Vineyard, a "Mindfulness Retreat", Aeva Doomes. I was not paid and they ended contract. They were very hard to work with and very rude, sending threatening emails on time frames, etc. Upwork answered no outreach to assist.
