Metroplex Eviction Services Billing/Collection Issues Ft Worth Texas

I hired Metroplex Eviction Services to do a writ of possession, and paid the total fees $910(court filing $285, labor crew $525.00, locksmith $100) on 12/9/2017. After court filing on 12/18/2017, my tenant moved out. Therefore the process stopped. On 12/20/2017 per my request, James Willis, the owner of Metroplex Eviction Services, said that he would send me the refund check for the labor crew and locksmith I paid but was not used. Since then I contacted him several times. He told me that he was busy or on vacation or the check is on the way... ...So far after more than 4 months, I have not received my refund. After 2/2/2018 he no longer answers my phone calls or replies to my text messages.
