This company does not pay money what's due to you

My case has been settled in the beginning of December 2017. My previous employer has paid them my settlement amount in the beginning of December 2017. It is now over 40 days later and I still have not received my money. I have sent emails with no response. I tried calling several times but to no avail. The office number now remains engaged. The sell themselves as a legal services company but they have terrible service.

I want my money!!!
