They charge a lot of fees, and if you pick the wrong freelancer and want a refund, they will not refund 100%. You as a costumer have to take all the risks and also pay a lot of fees. I lost 26 USD in the exercise because I got a freelancer that simply ghosted me after some days and I had to ask for a refund. They refunded but kept the fee. They could have kept the fee if I wanted to work with Workana again, but they lost a customer.
Also their chat system is bad and hard to use.
