First, I would be sure this is an attorney. Ask to see his Bar Card. He should be carrying a plastic card issued by the State Bar of Texas that says his name and his State Bar ID Number. If he does not have one with him, ask him for his number. If he will not give it to you then he is most likely not an attorney. Impersonating and attorney is a viokation of the Texas and Federal Fair Debt Collections Practices Act. Also, you do not have to hand over any money to him. Only a Constable or Depuity Sheriff with a Writ can seize money or property from you. Stop giving him money. As for showing up at work, tell him your employer does not allow such action. Se if your employer will give him a no trespass warning. Then, if he shows up again call the police and have him arrested for criminal trespassing.
You need to see an attorney about possibly filing for bankruptcy relief which will stop this individual from his harassing behavior.
Hire a consumer law attorney to sue him for possible FDCPA violations. At the very least, if you have counsel, he CANNOT talk to you or confront you in any way.
I would also file a bar complaint. This practice appears to be unethical.
