If the freelancer hasn't been delivering, you can request a refund. Your freelancer will then need to approve your request or decline and initiate a dispute. If a dispute is filed, our team will follow up and guide you through the process.
Just stop working with that unresponsive freelancer. Hire other freelancers and only continue working with the best ones.
The freelancer you hired first? He is wasting your time.
But if you choose to continue thinking about him or trying to get work from him, then it is your choice to waste your time.
