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.
