I have a client who I have provided services for over the past 4 months. He started out paying me, then stopped. He still scheduled hours of work for me and told me he would pay - now will not return my calls or emails. He also put a hold on his mail on Dec 13th - but still emailed me to come to his home to pick up a check. There was no check and he was not home. He has since stopped returning my calls.
Theft of services is something that you would need to contact the district attorney's office or the county attorney's office. Each one will have a division that deals with these types of matters. They may tell you that this is a civil matter and that you need to consider filing a civil suit. The Tarrant County DA's office has some very helpful people. I would start by giving them a call and seeing if you can file a report. Depending upon the value of the services provided, they may refer you to the county attorney's offices. Best of luck to you.
