We signed a contract about a website development: NDA + IP assignement and Total amount.
He overdue 15 days after the deadline and now I can't contact him any more by email and phone.
Also, he was always lying and late for in-person and phone meetings. So we had a conversation days ago and I proposed to him: Either he finish the project or refund the money, but we can't hold the money without any work done.
This web designer has a known public profile on the internet and it's very easy to track him on Facebook, Twitter and other social media. Also, I have information about this full time employer.
My question is: each webpage would cost $800, I paid $400 (I have the receipt, besides the contract). Is it worthy to take any legal action or should let it go.
